$broadcast is not working in Angularjs - angularjs

Question

I am using two controllers. When changes happen in one controllers it should get changed immediately in the other controller. I am using the $broadcast event to achive this.
My code:
My First controller
app.controller('configurationCtrl', function($scope, $http,Notification,$rootScope,$cookies) {
$scope.awssubmit=function(){
$scope.page_loader=true
$http.post("/insert_config_details",$scope.userdata).then(function(List){
if(List){
$scope.page_loader=false;
$cookies.put("bucket",$scope.userdata.bucket_name)
$scope.$broadcast('eventEmitedName', 'Some data');
Notification.success('<span class="glyphicon glyphicon-ok"></span> <strong>AWS Configuration details updated successfully.</strong>');
}
else{
$scope.page_loader=false;
Notification.error('<span class="glyphicon glyphicon-ok"></span> <strong>Error!!! Please try again later.</strong>');
}
$scope.awssave = false;
$scope.awstext=true;
})
}
});
My Second Controller:
app.controller('SidemenuController', function($scope, $http,$location,BucketService)
{
$scope.$on('eventEmitedName', function (event, data) {
console.log("Called"); //I am not getting this
value
console.log(data); // 'Some data' // I am not getting this
value
});
});
aws_submit() is called from my view and everything seems to work fine. But in SidemenuController I am not getting any data. Is there any mistake in my code?
Update:
My view :
<form id="awsform" method="post" name="awsform" class="form-horizontal" novalidate>
<div class="col-sm-6 four_module_config">
<div class="account_settings">
<div class="col-sm-12 heading_config" ng-hide="awssave">

Answer 1

If you want to send data from one controller to another controller using $brodcast than use $rootscope.$broadcast
$rootScope.$broadcast('eventEmitedName', 'Some data');
Second Controller
app.controller('SidemenuController', function($scope, $http,$location,BucketService) {
$scope.$on('eventEmitedName', function (event, data) {
console.log("Called");
console.log(data); // 'Some data'
$scope.bucket = data;
});
});
Note: Do not use $rootscope.$on as listener because $rootscope
listener are not destroyed . Instead it will create listeners stack

Answer 2

If you want to call one controller event into another there are four methods available:
$rootScope.$broadcast() if your controller are not in a parent / child relation.
If your second controller (event fired here) is a parent you can use $scope.$broadcast();
If your second controller (event fired here) is a child you can use $scope.$emit();
The best way to solve this would be to use a service -> Example of using a service to share data between controllers.
Note: You need to destroy $rootScope.$on() listeners manually avoid stacking events. This Difference between $rootScope.$on vs $scope.$on and this Do you need to unbind $scope.$on in $scope $destroy event? will help you understand the basics of using events.
View
<div ng-controller="MyCtrl">
<button ng-click="broadcast()">
broadcast
</button>
</div>
<div ng-controller="MySecondCtrl">
{{ test }}
</div>
AngularJS application
var myApp = angular.module('myApp', []);
myApp.controller('MyCtrl', function($scope, $rootScope) {
$scope.broadcast = function() {
$rootScope.$broadcast('test', 'testit');
}
});
myApp.controller('MySecondCtrl', function($scope, $rootScope) {
var registerScope = $rootScope.$on('test', function(test, args) {
console.log(args);
$scope.test = args;
});
// clean up, destroy event when controller get destroyed.
$scope.$on('$destroy', registerScope);
});
