Google's servers cache the KML content for some period of time. To force the rendered KML to update, add a cache busting parameter to the URL. I usually use a function of the date/time if I need to do it programmatically, or if it is just a one time edit a manual ?a=0 and incrementing that as I make changes works.

Something like this (if you don't have any other query parameters in the URL):

 var URL = filename+"?dummy="+(new Date()).getTime();
