title: ngChange-like functionality for the entire form
body: <p>I would like to do an equivalent of <code>ng-change</code> for the entire form whenever there is a change in one of its input fields.</p>
  
  <p>I know that since AngularJS 1.3 I have the debounce option but it applies only for a single input.</p>
  
  <p>I'm looking for a "debounce"/"on change" functionality that will apply for the entire form.</p>
