client.getCuratorListenable().addListener(new CuratorListener() {
    public void eventReceived(CuratorFramework curator, CuratorEvent event)
{
        //Your event handling code here.
    }
});

client.getChildren().watched().forPath("/bla");

Note the 'watched()' call.

This will return you all children currently under the path, and you will
receive a watch event whenever children are added or removed from the
parent node. Remember that you need to rewatch the parent node after each
event.
