Twitter Bootstrap in Rails

I generated views using this command

rails g bootstrap:themed Todo

it generated several views for my model.

I am using git and reverted the project to its former branch without the boostrap.

Now, I am trying to regenerate the views but it always returns this

   identical  app/views/manifests/index.html.erb

How do I force the bootstap generator to regenerate the views for my project?

TIA
