Rails - Jul 2006 - RJS and PeriodicalUpdater -- example?

In a controller, I''m trying to do

def do_some_periodic_thing
  render :update
    page << ''var foo = new
Ajax.PeriodicalUpdater("someDiv",
"/some/path", {asynchronous:true, frequency:1, evalScripts:true}
);''
  end
end

In the view, I have

<%= link_to_remote "Test Periodical", :url => { :action => 
"do_some_periodic_thing"}%>

But according to the log, /some/path never gets called.

Evidently, I''m doing something dumb or ignorant.

Can somebody give me an example of how this should be done? Or some 
pointers to web sites I should have found?

Thanks in advance...

I made some progress. I must have had an error in the code for making 
the PeriodicalUpdater. So now I''m getting the callbacks I expect.

However, I''m still not getting scripts from the callback method to be 
evaluated, though I set evalScripts:true in the PeriodicalUpdater. 
Instead, I get the script rendered as text.

So I still need a clue, if anybody''s got a spare... :-)
