Here is my approach to this requirement. Let me know if any further improvement can be added. The entire code can be found at the below URL:

Angular Save, Update and Delete

The sample screenshots from the code can be found here...

controller:


'use strict';

function MainController($scope, SharedService, ngDialog) {

  $scope.account_type_selected = "Savings";
  $scope.sharedService = SharedService;
  $scope.savingsMain = [];
  $scope.checkingsMain = [];
  $scope.addToCheckingsAccounts = {};
  $scope.addToSavingsAccounts = {};


  $scope.setAccountType = function (type) {
    if (type === "allAccounts") {
      $scope.showSavings = true;
      $scope.showCheckings = true;
    } else if (type === "savingsAccounts") {
      $scope.showSavings = true;
      $scope.showCheckings = false;
    } else if (type === "checkingAccounts") {
      $scope.showSavings = false;
      $scope.showCheckings = true;
    }
    $scope.account_type_selected = type;
  };

  $scope.$watch('savingsMain', function ($scope) {
    return $scope.savingsMain;
  });

  $scope.selectedAccountType = function (showAccount) {
    console.log(showAccount);
    if (showAccount === "Savings") {
      $scope.sharedService.accountType = "Savings";
    } else {
      $scope.sharedService.accountType = "Checkings";
    }
  };


  $scope.saveAccounts = function () {
    if ($scope.sharedService.accountType === "Savings") {
      $scope.addToSavingsAccounts = {
        "account_type": $scope.sharedService.accountType,
        "amount": $scope.sharedService.amount,
        "date": $scope.sharedService.date,
        "maturity": $scope.sharedService.maturity
      };
      $scope.showSavings = true;

      $scope.savingsMain.push($scope.addToSavingsAccounts);
    } else {
      $scope.addToCheckingsAccounts = {
        "account_type": $scope.sharedService.accountType,
        "amount": $scope.sharedService.amount,
        "bic": $scope.sharedService.BIC,
        "iban": $scope.sharedService.IBAN
      };
      $scope.showCheckings = true;
      $scope.checkingsMain.push($scope.addToCheckingsAccounts);

    }
    ngDialog.close();

  };

  $scope.deleteDataFromSharedService = function (accountType, item) {
    if (accountType === "Savings") {
      $scope.savingsMain = _.without($scope.savingsMain, _.findWhere($scope.savingsMain, { date: item }));
    } else if (accountType === "Checkings") {
      $scope.checkingsMain = _.without($scope.checkingsMain, _.findWhere($scope.checkingsMain, { bic: item }));
    }
  };

  $scope.closeDialog = function () {
    ngDialog.close();
  };

  $scope.accountTypeModel = [];


  $scope.prop = {
    "type": "select",
    "name": "account_type",
    "value": $scope.sharedService.accountType,
    "accountTypeData": ["Savings", "Checkings"]
  };

}

Answer 2

I would do it like this:

MainCtrl.js

(function () {
    'use strict';

    angular
            .module('app')
            .controller('MainCtrl', MainCtrl);

    MainCtrl.$inject = ['$scope', 'MainFactory'];

    function MainCtrl($scope, MainFactory) {

        $scope.details = MainFactory.details;

        function init() {
            MainFactory.get();
        }

        init();

        $scope.detailsModel = {
            "adformat_id": 1,
            "name": "Format 1",
            "size": "300x250"
        };

        $scope.add = function () {
            $scope.details.push($scope.detailsModel);
        };

        $scope.delete = function (index) {
            $scope.details.splice(index, 1);
        };

        $scope.edited = -1;
        $scope.editedModel = {
            "adformat_id": 0,
            "name": "",
            "size": ""
        };

        $scope.edit = function (index) {
            $scope.edited = index;
        };

        $scope.finishEdit = function (index) {
            $scope.details[index] = $scope.editedModel;
            $scope.edited = -1;
        };
    }
})();

MainFactory.js

(function () {
    'use strict';

    angular
            .module('app')
            .factory('MainFactory', MainFactory);

    MainFactory.$inject = [];

    function MainFactory() {

        var self = this;

        self.details = [];
        self.get = $http.get('data/home.json')
                .then(function (response) {
                    self.details = response.data;
                }).catch(function (error) {
                    // log error
                });

        return self;
    }
})();

index.html

<div ng-app="app">
    <div ng-controller="MainCtrl">
        <table>
            <tbody>
            <tr ng-repeat="details in detail">
                <!-- show-->
                <td ng-hide="edited === $index">{{detail.adformat_id}}</td>

                </td>
                <!-- Edit-->
                <td ng-show="edited === $index">{{detail.adformat_id}}</td>
                <td ng-show="edited === $index"><input type="text" ng-model="editedModel.name"></td>
                <td ng-show="edited === $index"><input type="number" ng-model="editedModel.size"></td>
                <td ng-show="edited === $index">
                    <button ng-click="finishEdit($index, editedModel)">Save</button>
                    <button ng-click="delete($index)">Detele</button>
                </td>
            </tr>
            </tbody>
            <tfoot>
            <tr>
                <td>
                    <button ng-click="add()">Add</button>
                </td>
            </tr>
            </tfoot>
        </table>
    </div>
</div>

It is just prototype, not tested, but it should help you to understand idea o two way binding in angular.
