I've never used Rails 3, and I do little enough Ajax development that I
have to check references every time. But with that in mind...

This is almost certainly not what you want. Even on Ajax requests,
you're requesting HTML, not JavaScript, so you're still dealing with the
format.html case. Just test request.xhr? to figure out if it was
responding to an Ajax call.

The .js says it's JavaScript. That's your cue to realize that you
shouldn't be doing it that way if you're wanting HTML. (Actually, I
believe js.erb is usually a sign of a design problem.)

Exactly. See above.
