Okaaaaay now I have it working, the trick is in this StackOverflow
post:
http://stackoverflow.com/questions/6183181/how-to-add-a-custom-widget-to-an-element
So in the end I did the following
in my jsni function
var newDiv = $doc.createElement('div');
the function returns the div as an Element which I in turn wrap in an
HTMLPanel using HTMLPanel.wrap and then I add the widget!
