You would need to use the same internal messaging protocol used by Gnoga to
do it the way you mentioned. While possible, a simple solution is to create
a hidden field and bind the On_Change event to that field in Gnoga. Then in
your JS every time you change the hidden field's value it will trigger your
handler on the Gnoga side.
