    <p>I have <a href="http://jsfiddle.net/ADukg/1403/" rel="nofollow">this fiddle example</a> where I am trying to set a value in an ng-repeat that lives in a different scope. This is a very basic example of a much bigger issue I am trying to solve. Basically I need to set a variable in the ng-repeat so that angular will update the template accordingly. The problem is that the template is in a child controller. So i use the $controller inject-able to access the variable. However, updating this variable does not cause the template to update. Even if I do a scope.$apply(). Anyone have any ideas? I am unsure on another way to do this...</p> <pre><code>var myApp = angular.module('myApp', []); myApp.directive("custdirective", function() { return { restrict: 'A', scope: 'false', link: function(scope, element, attr) { element.on("click", function() { anotherscope.addList(); }); } } }); function AnotherController($scope) { $scope.listtwo = new Array(); $scope.addList = function() { $scope.listtwo = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; } } function MyCtrl($scope, $controller, $rootScope) { anotherscope = $rootScope.$new(); $scope.anothercontroller = $controller(AnotherController, { $scope: anotherscope }); }​ </code></pre> <p>To do this correctly, one would create a service. I made an updated fiddle of the correct way to do this <a href="http://jsfiddle.net/ADukg/1412/" rel="nofollow">here</a> or:</p> <pre><code>var myApp = angular.module('myApp', []); myApp.factory("mySharedService", function($rootScope) { var sharedService = {}; sharedService.message = ''; sharedService.prepForBroadcast = function() { this.message = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; this.broadcastItem(); }; sharedService.broadcastItem = function() { $rootScope.$broadcast('handleBroadcast'); }; return sharedService; }); myApp.directive("custdirective", function() { return { restrict: 'A', scope: 'false', link: function(scope, element, attr) { element.on("click", function() { debugger; scope.handleClick(); }); } } }); function AnotherController($scope, sharedService) { $scope.listtwo = new Array(); $scope.addList = function() { $scope.listtwo = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; } $scope.$on('handleBroadcast', function() { $scope.listtwo = sharedService.message; $scope.$apply(); }); } function MyCtrl($scope, sharedService) { $scope.handleClick = function() { sharedService.prepForBroadcast(); }; } MyCtrl.$inject = ['$scope', 'mySharedService']; AnotherController.$inject = ['$scope', 'mySharedService'];​ </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
