Ember.js - How to trigger view method from controller?

Question

I\'m trying to call view method from controller, but no idea how to do this. From view I can easily call controller method like this.get(\'controller\').send(\'method\

This sounds like a good use for Ember.Evented. By using event subscription and dispatching you can avoid coupling your view and controller.

Simply mixin Ember.Evented:

Controller = Ember.Controller.extend(Ember.Evented)

Now you can call on and trigger methods on your controller, to subscribe to an event and then to kick off the event. So, in your view you might do:

didInsertElement: function () {
    this.get('controller').on('loginDidFail', this, this.loginFail);
}

And then in your controller call this.trigger('loginDidFail') to kick off your loginFail view method.

Remember to remove the handler after the view is dismissed... see the answer below.
