javascript - Twitter bootstrap jquery plugins compiled for production but not understood by the browser

I'm developing a 3.1 Rails app with Twitter Bootstrap using seyhunak's gem.

On the production mode, I was able to use basic bootstrap CSS and JS through pipeline precompilation:

RAILS_ENV=production bundle exec rake assets:precompile
 

Using the gem file :

group :assets do
   gem 'sass-rails',   '~> 3.1.5'
   gem 'coffee-rails', '~> 3.1.1'
   gem 'uglifier', '>= 1.0.3'
   gem "twitter-bootstrap-rails"
 end
 

And the application.js file:

//= require_tree .
 
 //= require jquery
 //= require jquery_ujs
 //= require twitter/bootstrap
 //= require bootstrap-tab
 //= require bootstrap-modal
 //= require bootstrap-dropdown
 //= require bootstrap-popover
 

The application worked fine except for for the bootstrap plugins such as modals and dropdowns. These plugins exist as static javascript libraries existing inside the vendor assets directory:

/vendor/assets/javascripts/bootstrap-dropdown.js
 ...
 

It seems to me that these files are not being precompiled, how can I manage to do so?

Update:

I opened the precompiled application.js and found that the plugins code do exist within it! I still have no idea why the browser is not able to load them properly.
