Sending dynamic variable from view to RJS file (AJAX)

How do I send a dynamic variable (album_id) too an ajax RJS file
copied below?

This works fine with a static span ID but Im not sure how to transfer

.rjs files are Ruby, so lose the erb:

   page.replace_html, @albums.reload.votes_count

Also, in HTML, ID's are supposed to start with a letter
(, so I would do
something like this:

   page.replace_html "albums_#{}", @albums.reload.votes_count

(and a similar construct in the view)
