Looks like readme error

[sadgb]

I was unable to *= require bootstrap-typeahead-rails but

*= bootstrap-typeahead-rails/bootstrap-typeahead

works good. I think you should update your readme

It should work as stated in the Readme.

The index file at [1] should get required when you do require bootstrap-typeahead-rails.

it doesn't work. Tried clean rails 4.2 application with line gem 'bootstrap-typeahead-rails' in my gemfile

You can take a look at the test app:

It works as stated in the Readme. Maybe you could check for differences.
