My first test

My first test

Hello everyone!!! :-)))

Here I am trying to make my new own toolbar plugin:

http://jquery.pastebin.com/RqnhHrFh

The problem I encounter is simply I see the div with ui-widget-header applied (a dark div) but the button doesn't look a flat button as like I see in this page http://jqueryui.com/demos/button/#toolbar but just a simple button even without the icon.
Then I tried also the click to see if maybe it goes calling the function with just a simple alert but it doesn't....
I would precise I loaded the smoothness CSS jquery-ui-1.8.4.custom.css...

Am I missing something maybe?

Any directions would be appreciate! Thanks a lot to everyone for your patience and help :-)))
Ciao,
Luigi
