title: Cannot read property '$valid' of undefined
body: <p>I have a form with a name field and two validations - required and max-length.
  When I enter correct value, the form in controller is showing valid and returning true. But on entering wrong data, $valid is not throwing false and simply says - </p>
  
  <pre><code>Cannot read property '$valid' of undefined
  </code></pre>
  
  <p>Why is the form getting undefined in this case? </p>
  
  <p>Jsfiddle <a href="http://jsfiddle.net/aroLabwy/" rel="noreferrer">here</a></p>
  
  <p>Thanks in advance</p>
