title: AngularJS submit on blur and blur on keypress
body: <p>I want to submit some data to the server when a input field is blurred. The User should also be able to blur the input field by pressing enter.</p>
  
  <p>Unfortunately this results in the following: <a href="http://docs.angularjs.org/error/%24rootScope%3ainprog?p0=%24apply">$rootScope:inprog: $apply already in progress error</a>.</p>
