Expand tree node by clicking onto the node label

Question

I have followed this example to expand the nodes with a clic on the tree :
[http://www.oracle.com/technetwork/developer-tools/adf/learnmore/20-expand-tree-node-from-label-169156.pdf]
My code:
JSPX:
<af:resource type="javascript" source="js/glasspane.js"/>
<af:tree value="#{bindings.OpcionesPadreView1.treeModel}" var="node"
rowSelection="single" id="t1" partialTriggers=":::cbNuevCpta"
binding="#{pageFlowScope.GestionDocumentos.t1}"
selectionListener="#{bindings.OpcionesPadreView1.treeModel.makeCurrent}">
<f:facet name="nodeStamp">
<af:commandImageLink text="#{node.Gesdopcach}" id="ot1"
action="#{bindings.LoadDir.execute}"
actionListener="#{bindings.LoadFile.execute}"
icon="/images/GestionDocumentos/folder20x20.png"
partialSubmit="true">
</af:commandImageLink>
</f:facet>
<af:clientListener method="expandTree" type="selection"/>
</af:tree>
Js:
function expandTree(evt) {
alert('In');
var tree = event.getSource();
rwKeySet = event.getAddedSet();
var firstRowKey;
for (rowKey in rwKeySet) {
firstRowKey = rowKey;
if (tree.isPathExpanded(firstRowKey)) {
tree.setDisclosedRowKey(firstRowKey, false);
}else {
tree.setDisclosedRowKey(firstRowKey, true);
When i clic on the labels the tree doesn't expand, the alert also is not shown. The problem could be the <af:resource>, but i have this tag in all my pages and all javascripts work. I also changed the commandLink with an outputText, but doesn't work.

At least the call the javascript works, but this line doesn't work, anybody know why?:
rwKeySet = evt.getAddedSet();
