dependent: :destroy doesn't work (has_many association)

My problem is as simple as is the title of this thread i have two classes

class Category < ActiveRecord::Base

  has_many :subcategories, dependent: :destroy

  accepts_nested_attributes_for :subcategories

end

class Subcategory < ActiveRecord::Base
  belongs_to :category
end

but when i hit link_to "Delete", category_path(category), method: :delete requested category gets destroyed, but all subcategories stay like nothing happened.

EDIT

Server Log:

Are you calling delete on category? you should call destroy instead.
