title: Using angularjs filter in input element
body: <p>I hope I haven't missed anything obvious in the doco, if I have I'm sure someone will help.</p>
  
  <p>I'm using asp.net webapi to return a DTO, with date fields. These are serialized using JSON.Net (in format '2013-03-11T12:37:38.693'). </p>
  
  <p>I'd like to use a filter but in an INPUT element, is this possible or should I create a new filter or directive to accomplish this?</p>
  
  <pre><code>// this just displays the text value
  &lt;input ui-datetime type="text" data-ng-model="entity.date" /&gt; 
  // this doesn't work at all
  &lt;input ui-datetime type="text" data-ng-model="{{entity.date|date:'dd/MM/yyyy HH:mm:ss a'}}" /&gt; 
  // this works fine
  {{entity.date|date:'dd/MM/yyyy HH:mm:ss a'}}
  </code></pre>
  
  <p>Is there any shortcut I'm missing?</p>
