title: tvOS - TVML data binding with carousel element
body: <p>I tried to create a template dynamically with the use of binding, and everything go fine with the element "grid" or "shelf", but when i use the element "carousel", the output is empty.</p>
  
  <p>I've created a sample project on GitHub that demonstrate the problem: <a href="https://github.com/christrato/TVMLTestApp" rel="nofollow noreferrer">https://github.com/christrato/TVMLTestApp</a></p>
  
  <p>The code is identically for both the example (grid and layout), instruction how to execute the test in readme file.</p>
  
  <p>Maybe a bug of the carousel layout, or i need extra settings for data binding and carousel?</p>
  
  <p>Thanks</p>
