Think that may be overkill - you'll be setting form to pristine even if other inputs are dirty.

>>>>Bear in mind that simply setting an inputs $dirty to false (even when there are no other dirty controls) will not cause the form $dirty to be re-evaluated. You may need something like this in your directive after $setPristine():

var dirty = false;

This will reset the form if all inputs are pristine.....

(Uses the control to reach up to the parent form)
