Merit doesn't add points to user after create action

Question

I've used this instructions for simply add score when a user creates a "solucion" (which is a kind of "answer" to a micropost). I have added the has_merit line to user.rb (user model).

I want to display the user points earned for that action at the show view. show.html.erb (for solucion):

<h2><span class="red"><%= current_user.points %></span><br>Points</br></h2>

It displays 0 points...

point_rules.rb:

module Merit
  class PointRules
   include Merit::PointRulesMethods

   def initialize
    score 5, on: 'solucions#create'
   end
  end
end

When I create a solucion with the current_user (already saving the user_id index and identifier to solucion), This is what my rails server output shows...

EDIT:

solucions_micropost.rb

  class SolucionsController < ApplicationController
  before_action :set_solucion, only: [:show, :edit, :update, :destroy]

  def index
    @solucions = Solucion.all
  end
  def show
  end
  def new
    @solucion = current_user.solucions.build
  end
  def edit
  end
  def create
    @solucion = current_user.solucions.build(solucion_params)

    respond_to do |format|
      if @solucion.save
        format.html { redirect_to @solucion, notice: 'Solucion was successfully created.' }
        format.json { render action: 'show', status: :created, location: @solucion }
      else
        format.html { render action: 'new' }
        format.json { render json: @solucion.errors, status: :unprocessable_entity }
      end
    end
  end
  def update
    respond_to do |format|
      if @solucion.update(solucion_params)
        format.html { redirect_to @solucion, notice: 'Solucion was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: 'edit' }
        format.json { render json: @solucion.errors, status: :unprocessable_entity }
      end
    end
  end
  def destroy
    @solucion.destroy
    respond_to do |format|
      format.html { redirect_to solucions_url }
      format.json { head :no_content }
    end
  end

  private
    def set_solucion
      @solucion = Solucion.find(params[:id])
    end
    def current_micropost
      @solucion = microposts.find_by(id: params[:id])
    end
    def solucion_params
      params.require(:solucion).permit(:solucion, :image, :micropost_id)
    end
end

user.rb:

class User < ActiveRecord::Base
  has_many :dreams
  has_many :microposts
  has_many :solucions

  has_merit
end

I had a problem with a migration when I installed the merit gem.
