Rails - Jul 2009 - Problem with jquery ajax call and js.rjs code

On one of my pages, i make a remote request to the update action of my
school_subscribers controller with a jquery ajax call.

In my log, i can see that the action executes fine, and the
corresponding js.rjs file is evaluated (i''m logging from inside that
file and it all seems fine).  I can see in the firebug console that i
get a 200 back from the remote request.  But, the code in the js.rjs
file isn''t actually executed.  I tried the simplest possible case of
having it just do

page.alert("hello")

but no joy.

I think that this is just a problem with how i have my jquery ajax
options set up - possibly the datatype option.  I tried omitting
datatype, and setting it to ''script'', or
''html'' but neither worked.

here''s my call:

    function updateSubscriber(id, paramString){
      jQuery.ajax({
        async:true,
        type: "PUT",
        datatype: ''script'',
        url: "/music_service/"+<%= @music_service.id
%>+"/school_subscribers/"+id,
        data: (paramString),
        error: function(msg){
          alert("Sorry, there was an error updating this subscriber");
        }
      });
    }

Can anyone see what i''m doing wrong?  Should i be using an ajax call in
this case?

Even more maddening - i decided to try to do it with a button_to_remote 
instead:

 <%=  button_to_remote "Mark as not paid", :url => 
music_service_school_subscriber_path(@music_service, subscriber, 
:school_subscriber => {:paid => 0}), :method => :put, :failure => 
"alert(''Sorry there was an error updating this
subscriber'')" %>

This generated the following, on the page (i added whitespace to make it 
more readable), which works, and appears to be exactly the same as i had 
when i hand-wrote the js!  wtf?  how come the code below works and the 
code above doesn''t?

<input onclick="jQuery.ajax({
    async:true,
    dataType:''script'',
    error:function(request){
      alert(''Sorry, there was an error updating this
subscriber'')
    },
    type:''put'',
   
url:''/music_service/4/school_subscribers/368?school_subscriber%5Bpaid%5D=0''
  });"
type="button" value="Mark as not paid" />
