title: Send empty POST field in Angular form
body: <p>I know angular do not send empty fields in form POST but i want exactly opposite of that. If a field is exist in form html then that field must be posted doesn't matter if its blank or have some data so that I can get that field in my function .</p>
  
  <pre><code> &lt;input type="hidden" class="form-control" ng-model="formData.field_name]" ng-trim="false"/&gt; 
  </code></pre>
