To fix the issue you can do If you want to assign the test function to $scope.value, just remove the () in the following line:
code :
$scope.value = $rootScope.test;

AngularJS Event not firing from $rootScope

AngularJS Event not firing from $rootScope

I wish this helpful for you It appears that the problem's caused by the Child scopes not being setup when the $rootScope.$broadcast event is fired.
I resolved the example by using:
code :
App.run(function($rootScope, $timeout){
    var text = 'Not So Static Now';

    $timeout(function(){
        $rootScope.$broadcast('event:staticText', text);
    }, 100);
}).$inject = ['$rootScope'];
App.controller('Ctrl1', function($scope, $rootScope) {
    $scope.staticText = "Static Text";

    var things = [
        'AngularJS',
        'StackOverflow',
        'JSFiddle'
    ];

    $scope.$emit('event:things', things);

    $scope.$on('event:staticText', function(e, args){
        $scope.$apply(function(){
            $scope.staticText = args;
        });
    });

}).$inject = ['$scope', '$rootScope'];

will be helpful for those in need If you don't un-register the event, you will get a memory leak, as the function you pass to $on will not get cleaned up (as a reference to it still exists). More importantly, any variables that function references in its scope will also be leaked. This will cause your function to get called multiple times if your controller gets created/destroyed multiple times in an application. Fortunately, AngularJS provides a couple of useful methods to avoid memory leaks and unwanted behavior:
code :
angular.module('test')
   .controller('QuestionsStatusController2',
   ['$rootScope', '$scope', '$resource', '$state',
   function ($rootScope, $scope, $resource, $state) {

    var cleanUpFunc = $rootScope.$on('action2@QuestionStatusController1', function {
         //write your listener here
    });

    $scope.$on('$destroy', function() {
        cleanUpFunc();
    });

   }]);

around this issue $rootScope.$emit only lets other $rootScope listeners catch it. This is good when you don't want every $scope to get it.
$rootScope.$broadcast is a method that lets pretty much everything hear it.

seems to work fine Calling a function from within an ng-repeat HTML Template will always cause an Infinite Digest error, because of the nature of the Digest cycle itself.
Essentially, the ng-repeat attempts to render the child nodes. In the child nodes, you are calling a function, which causes a Digest to occur. This new Digest causes the ng-repeat to start over, which causes the child nodes to be run again, which causes another Digest, ad infinitum.
