title: Cannot clear text in input text field in Ionic
body: <p>I'm new at Ionic and Angular. I try to create a post status like Facebook, my first task is when the user types any text and press the POST button I want the text in the input field to disappear, but it disappears in the first time when this view is a new load. </p>
  
  <p>When I try to type any text in the input field and press the POST button, the text won't disappear but function in the controller was called. Past, I use <code>label</code> tag but when I press the POST button <code>ng-click</code> didn't work so I change <code>label</code> tag to <code>div</code> tag but it work at the first time as I say above and I include cache is false it didn't work too.
