jquery UI combobox with a select onchange event - the onchange doesn't fire

http://jsfiddle.net/KJSvs/

I am using jQuery UI combobo开发者_如何学运维x with some select boxes like the one in the jsfiddle example above. The onchange attributes are populated dynamically. How do I get combobox to fire the original onchange event?
