Angular $rootScope.$broadcast() event caught twice in controller

Question

Broadcating event on button click :-

$scope.onButtonClick = function(){
    $rootScope.$broadcast(\'onButtonClick\');
}

And catching event in

Answer 1

As it turned out the multiple controllers were instantiated due to ng-controller declaration in html and also as part of state setup for ui-router.

The solution is to remove one of the declarations.
