title: AngularJS emit event from directive and update the DOM
body: <p>I looked in the internet before asking this question but i couldn't find the right answer.</p>
  
  <p>So, I want to emit an event from a directive to a controller and when this event occurs I want to update the DOM. I made a dummy <a href="http://embed.plnkr.co/211ybYEocJx2lYW5ee17/" rel="nofollow">plunker</a> please check it out.</p>
  
  <p>When I emit the event, the controller notice that but he didn't update the DOM. Please, see the console when firing the event.</p>
  
  <p>Can anyone explain to me?
  Thank you</p>
