title: dataTables 1.10.1 - no json data displayed
body: <p>Let's keep it short.
  I have simple dataTables (<strong>1.10.1</strong>) implementation to make but with code below nothing shows up. Not even a sigle error.</p>
  
  <p>For testing purposes data is loaded from the local server. It's a valid json and and it opens in a browser. Using e.g. Firebug in firefox I can see data loading in a background but I guess data fields from json are not properly accessed and that may be the source of the problem.</p>
  
  <p>Json is handled by the server properly. In the example below it is a flat file but I'm looking for a solution to handle either a flat file or dynamic output from server e.g. output from webapi.</p>
  
  <p>I have read <a href="http://datatables.net/examples/ajax/deep.html" rel="nofollow noreferrer">http://datatables.net/examples/ajax/deep.html</a> and many other sources like <a href="https://stackoverflow.com/questions/24171141/datatables-1-10-not-showing-results">DataTables 1.10 - Not Showing Results</a> but I didn't find any clues.</p>
  
  <p>Can you please take a look and help me with this one? ..and I'm really sorry for bothering if the solution is obvious :(
  Thanks for understanding.</p>
