title: Angular Validation on Submit with A Dotted Function Name
body: <p>I am trying to call a 'custom validation directive' by watching the ngModel.</p>
  
  <p>My submit function name is dotted.[sllr.save()]</p>
  
  <pre><code>&lt;div class="col-sm-10"&gt;&lt;input type="text" placeholder="must be numeric" class="form-control" name="meterCount" ng-model="sllr.entity.MeterCount" is-number&gt;
  &lt;div class="m-t-xs" ng-show="sllr.save.meterCount.$invalid &amp;&amp; sllr.save.submitted"&gt;
      &lt;small class="text-danger" ng-show="sllr.save.meterCount.$error.cvalid"&gt;&lt;/small&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p></p>
