Rails - Apr 2011 - change patial with change of the item in a select_tag

hi,
i would like to change a partial in my view with the change of the
item in a select_tag:

in the view:

<%= observe_field("payment_id", :url => {:controller
=>''user_admins'' ,:action =>
''rend_part''},:on => ''change'', :frequency
=> 0.1) %>
<%= select( "payment", "id", { "Visa" =>
"1", "Mastercard" => "2"}) %>

in controller :

def rend_part

   if params[:payment][''id'']  == ''1''
     render :partial => "patial_one"
   else
     render :partial => "patial_two"

   end
 end

And what happens when you do this? Does it work? Have you got a  
function in place to update the page?

In long-hand Prototype.js code, this would look something like this:

$(''my_picker'').observe(''change'',function(evt){
	new Ajax.Request(''rend_part'',{
		parameters:{
			payment_id:$F(''my_picker'')},
			onSuccess:function(transport){
				$(''some_div'').replace(transport.responseText);
			}
		}
	});
});

How you go about doing this with the Ajax helpers is an exercise for  
the student...
