How to update the treetable

I created a treetable with a treemodel based on database schema. I am trying
to refresh the treetable so that it will change it's data after some db
update.
I update viat the button event.the button event work but treetable doesn't
change.
To create treetable i have this on my page:

treeTable = new TreeTable("treeTable", createTreeModel(), columns);
treeTable.getTreeState().setAllowSelectMultiple(true);
treeTable.setRootLess(true);
treeTable.getTreeState().collapseAll();
creatForm.add(treeTable);

the createTreeModel code:
protected TreeModel createTreeModel() {
	DefaultMutableTreeNode rootNode = new DefaultMutableTreeNode();
	initTree(roleList, rootNode);
	TreeModel treeModel = new DefaultTreeModel(rootNode);
	return treeModel;
}

i add the button event like this:
protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
	roleList.clear();
	treeTable.updateTree(target);
	target.add(getForm(),treeTable);
}

Any idea or reference to documentation that explain this?
thanks.

Since Wicket's TreeTable uses Java's javax.swing.tree.TreeModel, I would
check out Oracle's tutorial on How To Use Trees (JTree).

More precisely the Dynamically Changing a Tree section:
http://docs.oracle.com/javase/tutorial/uiswing/components/tree.html#dynamic

See if that helps you.

~ Thank you,
