Please include the js files in your views by using the

<%= javascript_include_tag "filename_js", "data-turbolinks-track" => true %>

and please add your js file in assets.rb

Rails.application.config.assets.precompile += %w( filename_js.js )

Then run

rake assets:precompile

And start your rails server
