title: rspec changing attribute does not change other records
body: <p>I have this problem with testing, i have logic that reorders positions, for example if i have 1, 2, 3 and i give for 3 position 1 than 1,  2 will become 2, 3. Now i am trying to test this but i cant seem to figure this out!</p>
  
  <p>Here is my tests:</p>
  
  <pre><code>describe "order change" do
      let(:city){FactoryGirl.create(:city)}
      let(:place){FactoryGirl.create(:place, city_id: city.id)}
      let(:place_sec){FactoryGirl.create(:place, city_id: city.id)}
      let(:place_th){FactoryGirl.create(:place, city_id: city.id)}
  
  context "when editing record" do
        it "should go up and change middle records" do
          place
          place_sec
          place_th
          expect{
            place_id = Place.find(place.id)
            place_id.update_attributes(item_position: 3)
          }.to change(Place.find(place_sec.id), :item_position).from(2).to(1)
        end
      end
  </code></pre>
  
  <p>This does not work, what i need to do for this to work? Method for reordering is called with callback before_save</p>
