Is there a reason you wish to use `update` over just assigning to
`innerHTML` directly? I would suggest to go with the latter one, but
if you must:
Element.addMethods({
update: function(){ ... }
});
P.S. Also, don't forget that Element#update (among others) is
redefined for IE later during initialization time.
