I'm busy with building my own Wordpress Widget. Everything works fine except for the Wordpress media up loader.
I have created eight buttons and eight input text fields which should contain the url of the image that has been uploaded.

The click event is not being fired, probably because Wordpress outputs the HTML twice(Once in the bar of the available widgets and once in the bar currently active widgets).

Does anybody sees what I'm doing wrong?

Below you find my code.

Thanks in advance for the help!
