title: Ionic 2 - Ripple effect manually
body: <p>I want to add a ripple effect to the header of a card, because it is touchable. I don't want to make it a button, though, because</p>
  
  <ul>
  <li>The CSS would get a bit weird, as I want to do some custom things with it </li>
  <li>It doesn't really represent the semantics of what it is.</li>
  </ul>
  
  <p>So, my question is, I'm creating a directive for this sort of thing. How do I manually add the ripple effect on click/tap for it?</p>
  
  <p>Thanks!</p>
