EXT JS 4 - itemclick leaf event handling

Question

I'm new to sencha EXT JS and having a trouble to create a click event on my "Ext.tree.Panel".
I have used "EXT JS 4 CMD ( 4.2.1 )" to generate a default app and changed the default view / Main.js file to include a following code: http://pastebin.com/PGT7dwmC

At this stage what I'm trying to achieve is to create a simple click event when leaf item is clicked and the message "Clicked" will be pop up. The app compiles and opens correctly in web browser. However, no matter what I do, I cannot see any message on the console log or message pop-up when I click on the "tree.pannel" leaf item.

I have already spend days on this so any hints would be highly appreciated.

At the moment I'm trying to follow: Handling itemclick event on tree panel Extjs 4, but no success yet.

Update:

New Code: http://pastebin.com/bYYUhzm7

Still not working. Any additional ideas?

Thank you!!

Wrap itemclick config option in listeners:{} and move it one level up from root config to TabPanel config and it should work.
