Could not find generator 'jquery:datatables:install'

[biju-mouli]

I have this issue again - #143

Not sure how to re-open that issue; hence creating a new one.

I used
gem 'jquery-datatables-rails', github: 'rweng/jquery-datatables-rails'

and tried running
rails g jquery:datatables:install

I get this error:
Could not find generator 'jquery:datatables:install'. Maybe you meant 'devise:install', 'responders:install' or 'integration_test' Run rails generate --help for more options.
