Rails 3 and unobtrusive javascript

Question

I had a problem linking an unobtrusive js file to a view.

I have a name named.html.erb

...
<div id="fooBar">say bye!</div>
...

I also have a js file index.js.erb

$("#fooBar").html("say hello!")

I am currently receiving a bye by message because the javascript file is not executing.

What am I doing wrong?

It seems to me that js.erb is not used for this purpose. And I just need to add the script link to the regular .js file where the specific client logic is stored

Thank you Alex
