Can't reapply binding

[AlVipeo]

I'm trying to create an Upload control with jQuery and knockout and
I'm stuck with a problem - if user selects some file to be uploaded
and the upload started I need to show a dialog with upload progress.
After the Start is clicked I bind my VM to the dialog HTML and the
first time it works like a charm. When I select another set of files
and click Start again I don't see my VM bindings reapplied.

Here's the fiddle - http://jsfiddle.net/7Y3Ps/5/ .

Please help me out here.
Thanks in advance!
