angularjs - events in angular not binding to vm -


this question has answer here:

i new angular , cant seem figure out.

in controller using var vm = this syntax rather using $scope when trying attach $on event handler vm.$on not function error.

this works: 

$scope.$on('$viewcontentloaded', function () {      console.log(vm.myform); });

this not:

var vm = this;  vm.$on('$viewcontentloaded', function () {      console.log(vm.myform); });

could please explain why.

thanks james

$on method of $rootscope ,you cannot access elsewhere.in angular js,event communication happens through $rootscope.broadcast , $rootscope.emit,to subscribe event can use $rootscope.$on .to know more detail can read
