Undefined local variable or method `user_params' rails 4

So, I followed the rails for “Authentication from scratch” - http://railscasts.com/episodes/250-authentication-from-scratch

I understand that rails 4 do not use attr_accessible. I defined user_params in my user controller as a private method. For some reason, the rails give me an undefined error for user parameters. I am working on another rails application and I checked the post controller in it. This is exactly the same, except that it works. Any idea what the problem is here?

users_controller.rb

class UsersController < ApplicationController
  def new
    @user = User.new
  end

  def create
    @user = User.create(user_params)
  if @user.save
   redirect_to root_url, :notice => "Signed up!"
 else
   render "new"
   end
private

def user_params
  params.require(:user).permit(:email, :password, :password_confirmation)
 end

Error message: undefined local variable or method `user_params' for #
