title: Chart Title on Chart Click Event
body: <p>What I would like is the ability to click the title of a chart and have an action take place however the next best thing was the click event at the chart level.  I was able to locate the title of the chart from the event using the following:</p>
  
  <pre><code>this.title.element.innerHTML
  this.title.element.innerText
  this.title.element.childNodes[0].nodeValue
  this.title.element.firstChild.data
  this.title.element.firstChild.nodeValue
  </code></pre>
  
  <p>While all of the above work in IE8+ they do no work in FireFox.  Any ideas?</p>
