title: Boolean Filter for checkboxes in ng-model Angular
body: <p>item.imposed is either 1, or 0.</p>
  
  <p>In order for a checkbox to mark as checked, the value must be true or false.</p>
  
  <pre><code>&lt;input type="checkbox" ng-model="item.imposed"&gt;
  </code></pre>
  
  <p>You cannot use a filter inside of ng-model, how can this be accomplished simply and correctly?</p>
