Rails 3.1 Template Inheritance not working for js file?

Rails 3.1 has Template Inheritance feature built in, very nice. But when I tried to use it with unobtrusive javascript, it doesn't work.

I have a bunch of controllers all respond to :js and all of the xxx.js.erb are almost the same, so I moved them into app/views/applicatio开发者_JAVA技巧n folder, and then the controller just couldn't find the xxx.js.erb from that folder like it does for finding xxx.html.erb. Am I miss something or it isn't supported?

It seems to me your javascript files should be in the assets folder instead.
