title: how to show error message on submit button?
body: <p>Can you please tell me how to show an error message on submit button click ?.I am getting an error message after running the program (when I write required :true). I need to show an error message when a user submits the form. I am using this plugin <a href="https://github.com/McNull/angular-febworms" rel="nofollow">https://github.com/McNull/angular-febworms</a></p>
  
  <ul>
  <li>Can we get onchange event of select field ?</li>
  </ul>
  
  <p>In my example a red border is displayed when I run the application. I don't want this. I need this when a user clicks the 'submit' button</p>
