problems with a switch case from a select in my ui dialog title

Hey,

this is my code : http://jsfiddle.net/vc7wrsk9/1/

it isnt working in jfiddle, i downt know why.
But the code is working on my system.

Like i said, im using a drop down list ( select ) in my ui Dialog title.
And when i try to connect the values from the select with a switch case , it does nothing.

So, when i change the select from the 1st value to the 2nd in the title, it even doesnt trigger the alert i put in there.

any idea ?
