Well you should have an view for ajaxUpdate as the Javascript can get
the contents of that page fragment and insert it into the DOM where
the div is. When using ajax and non ajax requests. You should really
look into using the RequestHandler component as it will help switch
layouts and change output types if need automatically.

I just let the ajax requested action render an html fragment and jam
that back into the dom when the request is done. so ajaxUpdate would
need a view file, and since the ajax layout is an empty layout that is
all that will be returned.
