How to add a Independent local krpano events with Javascript Interface

I want to add a Independent local krpano events with Javascript Interface and don't know how to add. The troublesome friends share the method, thank you.

var mypano=document.getElementById("krpano");
mypano.set("events.name","skin_events");
mypano.set("events[skin_events].onxmlcomplete","js(initPano());")

But do not execute initPano function

Thank you very much.
