Understanding Inter-Control Operations in angularJS

I would like to use angularJS to perform certain actions from one controller in another controller. Is there a way?

Example
HTML side
ng-click to call sampleA() on controller A
↓
On the JSide
Run controller B's sampleB() from controller A's sampleA

angularjs

$rootScope to $broadcast to send events to the descendants of $rootScope, that is, all scope.

DEMO

myApp.controller('A',['$scope','$rootScope', function($scope,$rootScope){
  $scope.sampleA=function(){
    $rootScope.$broadcast('myevent');
  };
}]);

myApp.controller('B', ['$scope', function($scope){
  $scope.$on('myevent', function(event,...args){
    $scope.sampleB();
  });
  $scope.sampleB=function(){
    // do something
  }
}]);
