title: How do I navigate (push) to a page in Ionic 2?
body: <p>I've followed the documentation for Ionic 2 and couldn't find the way to push/modal a page.</p>
  
  <p>I followed the tutorial, but when I click on the button nothing happens.</p>
  
  <p>The official <a href="http://ionicframework.com/docs/v2/components/#navigation" rel="nofollow">guide</a> didn't explain Page Navigation too well.</p>
  
  <p>Can someone explain the process?</p>
