Ruby Live Tree Error

The website I am working (http://xoth.media.mit.edu:8000/ica/view) on
uses a LiveTree add-on that should update a portion of the page to
reflect the components of the tree when the appropriate textbox is used.
For some reason, instead of simply updating a portion of the page, the
site is opening a whole new page with on the partial updated component
displayed. Why is it doing that and how can I fix it?
