How to check that while XML is loaded with all the attributes like scene hotspots etc using javascript

I have function which needs to be called after scene is fully loaded with their hotspots using javascript.
Belo is my code :-

loadKRpanoView(xmlFile, swfFile);
this.krpanoObj = document.getElementById('krpanoSWFObject');
this.krpanoObj.set('events.onloadcomplete', this.callHotspotNames());
this.krpanoObj.set('events.keep', true)

Here I have tried event on load event but it not working anyway it is calling before scene is fully loaded so the callHotspotNmae is calling anyway

Any Help will be appreciated
