Rails - May 2006 - return value from collection_select

Hi everyone

I am trying to get the return value from collection_select helper 
method.  Here is what I did

collection_select(''product'', ''product_id'',
@products, ''id'', ''name'', {},
{:onchange => remote_function(:url => {:action => :myFunction},
 :with => "this[this.selectedIndex].value")})

then in my controller''s myFunction, I get the value using
request.raw_post

Is there a better way to do the same thing? should I use select instead 
of collection_select?

Thank you very much!

Victor
