title: file.js.coffee.erb not updating
body: <p>I have some Javascript (initially CoffeeScript) code that uses data from the database. I create the data array with .erb, then do the code with .coffee, and finally use the .js. Fairly standard stuff. The problem is that the javascript served to the browser is cached and never refreshes, even after a server restart or assets:clean.</p>
  
  <p>To get the javascript to refresh I have to delete the tmp folder contents and start the server.</p>
  
  <p>Q1. How can I make the javascript refresh on every request? I tried to inline the code using Coffeebeans to render a file with the code but the code appears html encoded.</p>
  
  <p>Q2. Will this even work on Heroku? (it only accepts precompiled assets)</p>
