Uncaught ReferenceError: simpleDatatables is not defined

I had it working before in another project but in a new project, I get the error shown in the title of this issue. I think it might be due to some JavaScript load order but can't identify it. Any ideas?

I had to manually copy the .js and .coffee files from the site's gem/simple_datatables-0.3.0/vendor/assets/javascripts folder into my project's app/assets/javascripts folder. Now it works.

I thought //= require simple_datatables in my application.js (the "manifest") would have done the trick.

I checked my Rails.application.config.assets.paths in the Rails console, and it does include the expected component:

...../RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/simple_datatables-0.3.0/vendor/assets/javascripts
