[Freeswitch-users] firing events from javascript - working example needed

I noticed the wiki has an example of sending a custom event from javascript: http://wiki.freeswitch.org/wiki/Javascript_Event , but I can't make it work. It doesn't fail or cause an error. But I never see an event on my listener script. Can someone confirm that this example does in fact work? or provide me with one that does? --Stephen
