Change helper including with helpers method
user
```ruby
class ContactsController < ApplicationController
  before_filter :authenticate_user!
  
  def index
    @contacts =
      current_subject.
        contact_subjects(:direction => :sent, :relations => params[:relation]){ |q|
          q.alphabetic.
            letter(params[:letter]).
            search(params[:search])
        }

    respond_to do |format|
      format.html { @contacts = Kaminari.paginate_array(@contacts).page(params[:page]).per(10) }
      format.js { @contacts = Kaminari.paginate_array(@contacts).page(params[:page]).per(10) }
      format.json { render :text => @contacts.map{ |c| { 'key' => c.actor_id.to_s, 'value' => self.class.helpers.truncate_name(c.name) } }.to_json }
