title: .draggable revert back to original position after link has been clicke
body: <p>Struggling here, I'm Using .draggable on a div which works fine but I also need a link so that once a user has dragged the div anywhere on the page they can "Reset" it back to it's original position.</p>
  
  <pre><code>$(function() {
      if (! /iphone|ipad|ipod|android|blackberry/i.test(navigator.userAgent.toLowerCase())) {
          $( "#race_charts_container" ).draggable({ revert: false, cancel: "#graphs_content"});
      }
          });
  
  
  $("#btnReset").click(function() {
      $("#race_charts_container").animate({
             left: '+=50px',
             top: '+=50px'
      });
  });
  </code></pre>
