Components, where to put my helpers?

I understand how and where to put my component controllers, models and
views in the component folder (belo app), and writing the use
uses_component_template_root in the controllers, but where should I put
my helpers… I tried in the standard helpers folder and writing
includes :

include ApplicationHelper
include MyComponentControllerHelper

but the view doesn’t find the helpers at all…

any clue ?
