title: Trigger form validation on ng-click
body: <p>I created a <a href="http://plnkr.co/edit/PCTf4VPkgooWL15iSfGL?p=preview" rel="nofollow">Plunker</a> that displays a simple form with a required email field. The validation works when the user types in the email but is there a way to trigger the validation when clicking on the button. I don't want to disable the button based on the form validity.</p>
