use-jquery not working

[bhelx]

I used the command:

bhelx$ rails generate event_calendar --use-jquery

and it tells me:

Using jQuery for scripting
create public/javascripts/event_calendar.js
............
............

But it still uses prototype. Afterwards I run the command:

bhelx$ rails destroy event_calendar

and it tells me:

Using Prototype for scripting
remove public/javascripts/event_calendar.js
............
............

this is Ruby 1.9.2 and Rails 3.0.9

The contents of even_calendar.js show the jquery version. Is jquery supposed to be included?
