Hi, in my situation I have

class GranParent
include Mongoid::Document

embeds_many :parents, cascade_callbacks: true
end

class Parent
include Mongoid::Document

embeds_many :children, cascade_callbacks: true
end

class Child
include Mongoid::Document

mount_uploader :image, ImageUploader

embedded_in :parent
end

When I change a Child through GranParent without changing Parent, Mongoid doesn't fire callbacks on Child. Any idea how to work around?
