fire treeloader with new url on node click extjs 3

Question

I am trying append child nodes to a tree node when the node is clicked. It is required to fire a tree loader with desired url whenever a particular node is clicked.

I tried something like this

tree.dataUrl = '/zport/clusterSysReg?args=/directory/'+node.attributes.name;
//alert(tree.dataUrl);
node.reload();

whenever I click on a node the child nodes are created but not with the new url, but with the old url, I also tried node.load instead of node.reload(), but I am getting an error .........

Any idea how to proceed

Here is the solution to the above problem (took me whole day to solve this) Inside the listner function added the following lines

listeners: {
   'render': function(tp){

            tp.getSelectionModel().on('selectionchange', function(tree, node){

            tp.getLoader().dataUrl = '/zport/clusterSysReg?args='+node.attributes.name;
            tp.getLoader().load(node);
            ...................... 
            ......................
            }
}
