AngularJS and typescript broadcast

问题

I have following problem. I want to broadcast array of albums to another controller. Structure of my controllers : Parent - multimediaController, child - multimediaAlbumController. I am sending variable, but i cannot receive i, don't know why actually..

multimediaController.ts

export class MultimediaController {
   $scope;
   static $inject = ['$scope'];
   constructor($scope){
     this.$scope = $scope;
   }
   changeAlbum(){
       this.$scope.$broadcast('prod', console.log("sending") );
   }
}

multimediaAlbumController.ts

export class MultimediaAlbumController{
   $scope;
   static $inject = ['$scope'];
   constructor($scope){ 
      this.$scope = $scope;
   }
   brodRec(){
     this.$scope.$on('prod', () => {
            console.log("receiving");
        });
   }
}

i am getting in console - sengind, but cannot get receiving. What am i doing wrong?

please make $scope variable public.

constructor(public scope:ng<IScope>) {
 this.$scope = scope;
}
