Rails: link_to with: remote => true not working

Question

I am trying to implement a voting system like here in Stack Overflow. (Using Rails 3) I want the vote to be done without reloading the page, so I have this code

link_to("/tags/#{tag.id}/upVote", :remote => true )

And so, in my / views / tags directory, I have a file called _upVote.js.erb, which I thought would be called when this link is clicked, but it doesn’t. It tries to treat upVote as HTML, and this is the error I get

Missing / upVote template tag with {: formats => [: html]

Also, here is what I have in the routes file

match "tags/:id/upVote" => "tags#upVote"

Any ideas how I can make this work?
