Built a modal popup example using syarul's jsFiddle link. Here is the updated fiddle.

Created an angular directive called modal and used in html. Explanation:-

HTML

<div ng-controller="MainCtrl" class="container">
  <button ng-click="toggleModal('Success')" class="btn btn-default">Success</button>
  <button ng-click="toggleModal('Remove')" class="btn btn-default">Remove</button>
  <button ng-click="toggleModal('Deny')" class="btn btn-default">Deny</button>
  <button ng-click="toggleModal('Cancel')" class="btn btn-default">Cancel</button>
  <modal visible="showModal">
      Any additional data / buttons
  </modal>
</div>

On button click toggleModal() function is called with the button message as parameter. This function toggles the visibility of popup. Any tags that you put inside will show up in the popup as content since ng-transclude is placed on modal-body in the directive template.

var mymodal = angular.module('mymodal', []);

mymodal.controller('MainCtrl', function ($scope) {
    $scope.showModal = false;
    $scope.buttonClicked = "";
    $scope.toggleModal = function(btnClicked){
        $scope.buttonClicked = btnClicked;
        $scope.showModal = !$scope.showModal;
    };
  });

mymodal.directive('modal', function () {
    return {
      template: '<div class="modal fade">' + 
          '<div class="modal-dialog">' + 
            '<div class="modal-content">' + 
              '<div class="modal-header">' + 
                '<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>' + 
                '<h4 class="modal-title">{{ buttonClicked }} clicked!!</h4>' + 
              '</div>' + 
              '<div class="modal-body" ng-transclude></div>' + 
            '</div>' + 
          '</div>' + 
        '</div>',
      restrict: 'E',
      transclude: true,
      replace:true,
      scope:true,
      link: function postLink(scope, element, attrs) {
        scope.title = attrs.title;

        scope.$watch(attrs.visible, function(value){
          if(value == true)
            $(element).modal('show');
          else
            $(element).modal('hide');
        });

        $(element).on('shown.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = true;
          });
        });

        $(element).on('hidden.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = false;
          });
        });
      }
    };
  });

UPDATE

<!doctype html>
<html ng-app="mymodal">


<body>

<div ng-controller="MainCtrl" class="container">
  <button ng-click="toggleModal('Success')" class="btn btn-default">Success</button>
  <button ng-click="toggleModal('Remove')" class="btn btn-default">Remove</button>
  <button ng-click="toggleModal('Deny')" class="btn btn-default">Deny</button>
  <button ng-click="toggleModal('Cancel')" class="btn btn-default">Cancel</button>
  <modal visible="showModal">
      Any additional data / buttons
  </modal>
</div>

        var mymodal = angular.module('mymodal', []);

mymodal.controller('MainCtrl', function ($scope) {
    $scope.showModal = false;
    $scope.buttonClicked = "";
    $scope.toggleModal = function(btnClicked){
        $scope.buttonClicked = btnClicked;
        $scope.showModal = !$scope.showModal;
    };
  });

mymodal.directive('modal', function () {
    return {
      template: '<div class="modal fade">' + 
          '<div class="modal-dialog">' + 
            '<div class="modal-content">' +

                '<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>' + 
                '<h4 class="modal-title">{{ buttonClicked }} clicked!!</h4>' + 
              '</div>' + 
              '<div class="modal-body" ng-transclude></div>' + 
            '</div>' + 
          '</div>' + 
        '</div>',
      restrict: 'E',
      transclude: true,
      replace:true,
      scope:true,
      link: function postLink(scope, element, attrs) {
          scope.$watch(attrs.visible, function(value){
          if(value == true)
            $(element).modal('show');
          else
            $(element).modal('hide');
        });

        $(element).on('shown.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = true;
          });
        });

        $(element).on('hidden.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = false;
          });
        });
      }
    };
  });

    </script>
</body>
</html>

UPDATE 2 restrict : 'E' : directive to be used as an HTML tag (element). Example in our case is

<modal>

Other values are 'A' for attribute

<div modal>

'C' for class (not preferable in our case because modal is already a class in bootstrap.css)

<div class="modal">

If you are using bootstrap.js then the below code might be useful. This is very simple. Dont have to write anything in js to invoke the pop-up.

Source :http://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_modal&stacked=h

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>

  <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

<body>

<div class="container">
  <h2>Modal Example</h2>
  <!-- Trigger the modal with a button -->
  <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>

  <!-- Modal -->
  <div class="modal fade" id="myModal" role="dialog">
    <div class="modal-dialog">

      <!-- Modal content-->
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</button>
          <h4 class="modal-title">Modal Header</h4>
        </div>
        <div class="modal-body">
          <p>Some text in the modal.</p>
        </div>
        <div class="modal-footer">
