title: jQuery closest('tr') not working in iOS
body: <p>I have the following code</p>
  
  <pre><code>fnDrawCallback: function() {
      $("#rqTable tbody tr td .fa-edit").closest('td').on('click', function() {
          // log for testing
          console.log(this);
          console.log(this.closest('tr'));
          console.log(this.closest('tr').id);
      });
  }
  </code></pre>
  
  <p>It works as expected in IE, Chrome, Firefox, Andriod but not in Safari or on an iPhone.  </p>
  
  <p>this is a screen shot of the console in firefox

  <p>Is there something I should be doing different to account for the iOS difference?</p>
