collection_check_boxes | checked value setting issue

ff.collection_check_boxes(
    controller,
    Adm::ABILITY_ACTIONS,
    :second,
    :first,
    { checked: controller.include?(second) },
)

When I try to use collection_check_boxes method, I can not set checked attribute for elements. Am I missing something, or is this a missing point?
