Call function from delyed job in rails

I have one function, that have been working in delayed job.

class TestDelay < ActiveRecord::Base
  def start_worker
     tc = TestController.new

     #Here calling that main function
  end
end

also i have one other class

class TestController < ApplicationController
  before_filter :filter1, :filter2

  def follow_function
    #Doing the main portion
  end

  protected
  def filter1
  end

  def filter2
  end

end

In the class TestController has two filters, that will work on every action, there setting the instance variables on that filters, and using that in my follow_function. So the issues are when i am trying to call the follow_function from the delayed job method start_worker, i need to set the instance variables in that filters.

so what i tried something like that i put one function in TestController class like

def init_variables(names)
  #filter1(names)
  #filter2(names)
end

class TestDelay < ActiveRecord::Base
  def start_worker
     class_name.init_variables(params)
  end
end

and i tried to passing arguments in before_filter, but its totally failed and getting weird. Is this the correct way to do this?
