submitting a form that is in a dialog

Hi!
I have the following problem:

I've created a dialog, which works correctly.
The "ok"-button of this dialog shall submit the form.
But this action doesn't seem to work, because nothing happens.

Here is the body-part: http://pastebin.com/bYeeiqyt

On line 38 you can see the submit function (I tried various).
On line 47 I specified the form.

I hope, that someone can help me.
