mschadegg on "Wordpres TinyMCE button, will not open window"

I have a problem when trying to make a plugin for wordpress TinyMCE editor. I will have a button, that opens af dialog window, where I can pick some links.

The button shows fine, but nothing happens when clicking it.

See the code in my question on StackOverflow:

Cann anyone see what is wrong?
