I think it's only going to be defined for JS executed via WebKit API, 
not for JS that's defined by your web content? Otherwise random web 
content would be able to talk to your internal message handlers, and 
that's probably not good.

Try webkit_web_view_run_javascript() in the UI process, or 
jsc_value_object_invoke_method() in the web process.
