title: Handling call back in jQuery treetable
body: <p>I am new to Javascript and jQuery world. I am trying to display a tree table using the jQueryTree table at the link below.</p>
  
  <p><a href="http://ludo.cubicphuse.nl/jquery-treetable/" rel="nofollow noreferrer">http://ludo.cubicphuse.nl/jquery-treetable/</a></p>
  
  <p>it provides a few call back functions</p>
  
  <ul>
  <li><code>onInitialized</code> Callback function fired when the tree has been initialized.</li>
  <li><code>onNodeCollapse</code> Callback function fired when a branch is collapsed.</li>
  <li><code>onNodeExpand</code> Callback function fired when a branch is expanded.</li>
  <li><code>onNodeInitialized</code> Callback function fired when a node has been initialized.</li>
  </ul>
  
  <p>I understand what the call back functions are. I am having trouble trying to code for in Javascript.</p>
  
  <p>Can any help me understand how I can handle these call back functions. I am trying to get the id of the selected node. </p>
  
  <p>Any help will be appreciated.</p>
