  before_save :action1
  before_save :action2

  insert_before_save :new_action1, before: :action1

end

Sample.__callbacks[:save].map(&:filter) #=> [:new_action1, :action1, :new_action2, :action2]

end

SampleJob.__callbacks[:perform].map(&:filter) #=> [:new_action1, :action1, :new_action2, :action2]

SampleJob.delete_before_perform :new_action1

SampleJob.__callbacks[:perform].map(&:filter) #=> [:action1, :new_action2, :action2]
