title: trouble with highchart and .clone()
body: <p>I don't understand how I'm supposed to use jQuery .clone() when i'm cloning an highchart.
  I know that .clone() doesn't link the methods on objects. So the clone of the highchart looked correct, but you couldn't interact with it anymore.
  SO, I've been trying the following :</p>
  
  <pre><code>function clonage(src){
      var clone = src.clone(false);
      if (clone.hasClass("highchart")){
          clone.highcharts({});
      }
  }
  </code></pre>
  
  <p>By doing this, I've got back the interactions with the chart (the chart is blank), but this is destroying the original of the clone (ie src) which is now only a blank widget.
  I would like to be able to recreate the exact same chart without embedding all the chart information to recreate it.
  If anyone has an idea in order to do this?</p>
