title: Trigger validation of all fields in Angular Form submit
body: <p>I'm using this method: <a href="http://plnkr.co/edit/A6gvyoXbBd2kfToPmiiA?p=preview" rel="noreferrer">http://plnkr.co/edit/A6gvyoXbBd2kfToPmiiA?p=preview</a> to only validate fields on blur. This works fine, but I would also like to validate them (and thus show the errors for those fields if any) when the user clicks the 'submit' button (not a real submit but a data-ng-click call to a function)</p>
  
  <p>Is there some way to trigger validation on all the fields again when clicking that button?</p>
