Is before_action outside the scope of private methods?

In the controller:

before_action { |controller| controller.param_policy(action_name) }.

Also in the same controller is the param_policy method. Under private. Why is rails complaining with: 

private method `param_policy' called for #<SomeController:0x007fc80196bc40>

The code:

class SomeController < ApplicationController
  before_action { |controller| controller.param_policy(action_name) }

  private

  def param_policy(action_name)
    # ...
  end
end

Is before_action outside the scope of private methods?

The correct syntax in rails 4 to append a callback to a controller is:

before_action :param_policy

In rails 3, it was before_filter. Seeing the error, it seems that you are calling param_policy on an instance of class SomeController, which cannot call the private method, as it is a basic OOPS concept.
