Unable to trigger an action tied to a link

[yoursurrogategod]

This is my code:

http://bin.cakephp.org/view/2118176254

 

 

When I first start it up, I enter a username and then proceed to click on the Exit above. I was expecting some sort of a pop-up asking me if I _really_ want to exit. But, nothing happens.

 

 

I'm running Firefox and I checked in my about:config, Javascript is enabled. jQuery is located one directory above.

 

 

I got this idea from this tutorial:
