Angular filter and order elements on click

Question

I\'m trying to filter a list of items (grabbed from JSON) onclick. I pull the data once from the server then would like to filter/order the elements using Angular.

I would wrap the entire functionality inside a parent controller with the tab change and category select functions inside that parent controller (the child scopes will inherit this) so that the scope variables can be shared down for the filters and order By:

HTML:

<div ng-controller="ListController">
<div class="categories" ng-controller="CategoryController">
  <ul ng-repeat="category in categories">  
    <li ng-click="sendCategory(category)">{{category.name}}</li>
  </ul>
</div>

<div class="tabs" ng-controller="tabsController">
  <ul>
      <li ng-click="tab(1)">Recent items</li>
      <li ng-click="tab(2)">Popular items</li>
  </ul>
</div>

<div class="container">
  <div class="left" ng-controller="ItemController">
    <div class="itemList">
        <div class="item" ng-repeat="item in items | filter:search | orderBy:sort"> 
            <h3 ng-click="viewDetail(item)">{{item.title}} - {{item.date}}</h3>
            <p>{{item.description}}</p>
        <a ng-click="viewDetail(item)">View full item details</a>
        </div>
    </div>
  </div>
</div>
</div>

Here is the parent controller:

myApp.controller('ListController', function($scope, $route, $location, $http, Categories){

 $scope.sort = function(item) {
   if (  $scope.orderProp == 'date') {
        return new Date(item.date);
    }
    return item[$scope.orderProp];
  }

  $scope.sendCategory = function(category) {
    // How can I pass this value to ItemController?
     $scope.search =category.name;
  };

   $scope.orderProp='date';

    $scope.tab = function (tabIndex) {
     //Sort by date
      if (tabIndex == 1){
        //alert(tabIndex);
        $scope.orderProp='date';

      }   
      //Sort by views 
      if (tabIndex == 2){
        $scope.orderProp = 'views';
      }

   };

})

** Update **

I've updated the controller to sort the dates correctly since they need to be parsed first.
