Subject: module_eval: create method that contains value passed to it?

This is a Rails example, but I think the problem is a general Ruby 
matter.

I am using class_eval within a class method, foobar(), to have it create 
an instance method, get_foobar(). I am passing a value ("testing testing 
123") to foobar() that I want to make part of get_foobar(). However, I 
can't seem to include this value in the output of get_foobar().

Where I want the "render" line to output "A start testing testing 123 
end O", it only outputs "A start end O". Extremely grateful for any 
help. Code:

	class HelpController < ApplicationController

	  def self.foobar(v)

	    class_eval %q{
	      def get_foobar()
	        "start #{v} end"
	      end
	    }

	  end

	  foobar "testing testing 123"

	   def index
	    render :text => "A "+get_foobar+" O"
	  end

	end
