how find selector on page?

please help solve the problem. i use rails4 + rspec2 + pry + capybara.

my test:
describe 'albums?' do
  it 'check albums page' do
    user = FactoryGirl.create(:user)
    visit user_albums_path(user.id)
    expect(response.status).to eq(200)
    expect(response).to render_template(:index)
    binding.pry
    expect(page).to have_selector('.albums_list_label')
  end
end

i run in console:
rspec spec

and i output DOM response:
[1] pry(#<RSpec::ExampleGroups::PersonsController::Albums>)> puts
page.body

result:
.....
........
<h1>
  <span class="albums_list_label" id="albumsListLabel">Список
альбомов</span>
    <span class="name">:: us7</span>
</h1>
.........
............

but when i run:
continue

i get follow error message:
.F............
Failures:
  1) AlbumsController index action check albums page
     Failure/Error: expect(page).to have_selector(".albums_list_label")
       expected to find css ".albums_list_label" but there were no
matches

problem: element with class .albums_list_label contains in server
response (DOM), but test is failed
