title: The model is updating, but not the UI
body: <p>I am using the <a href="https://github.com/katemihalikova/ion-datetime-picker" rel="nofollow">ion-datetime-picker</a> in my ionic project. Everything works fine when I debug it in web browser. When I run it on real device, I found a problem. The input text doesn't update. I check it with <code>chrome://inspect/#devices</code>, I see that the value of the input (model) changes even though the text in the input not changing. </p>
  
  <p>I have added new issue <a href="https://github.com/katemihalikova/ion-datetime-picker/issues/50" rel="nofollow">here</a>, hopefully anybody here can help too. Many thanks in advance.  </p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I have tried to add a callback too in this plugin with ng-click, and pass the value accordingly to the scope and after that do some <code>triggerHandler</code> to the input. </p>
  
  <pre><code>    $scope.changeme = function(val) {
          alert(val)
      }
  </code></pre>
  
  <p>The strength is it alert the value three times. The first time it alert the full date description, the second time it alert with time format as expected like <code>13:30</code>, and finally the last time it only alert <code>Nan:Nan</code></p>
  
  <p>I also did $scope.$apply() and it still doesn't help. </p>
  
  <p>Please help. I spent my whole night only for this thing. Thanks in advance. </p>
