title: iOS onclick not firing
body: <p>I want to know when a user clicks on my textarea.</p>
  
  <p>Using the following code:</p>
  
  <pre><code>document.getElementById("boxtextarea").onclick = function (e) {
      alert('clicked');
  }
  </code></pre>
  
  <p>Works fine in all browsers except for safari on iOS.</p>
  
  <p>Any ideas how to capture when a user enters / leaves the textarea?</p>
