rail 3.2: how do I use number helpers or application helpers inside a custom helper?

I have a custom helper module, CalendarHelper. Some of my views then use custom helper methods to display a calendar.

When I try to use any view helpers inside my custom helpers, such as number_to_currency(), I get an undefined method error, even if I add 

include ActionView::Helpers::NumberHelper

to my CalendarHelper.

I also tried adding a method to application_helper:

  def as_dollars_pretty(price)
    number_to_currency(price, :precision => 2, :unit => '$')
  end

then in my custom helper I added

include ApplicationHelper

but when I try to use as_dollars_pretty(123.45) in my custom calendar helper I get the same undefined method error.

This works for me

module TestHelper
  include ActionView::Helpers::NumberHelper

  def foo
    number_to_currency 123
  end
end

include TestHelper

puts foo
