Manually triggering the validations

The angular-ui-form-validation directive adds a listener on the scope object that listens for the runCustomValidations event on which it will perform its custom validation. This event is triggered whenever there is a change event in the input field.

You may manually invoke 'runCustomValidations' event on the scope of your controller by emitting or broadcasting this event.

Here's a plunker demonstrating validations being manually triggered in the controller: http://plnkr.co/edit/gMAj1v?p=preview
