title: jquery datatables default sort not working
body: <p>I have a 4 column table, I want the first 3 columsn to be sortable by the user, but not the 4th, this is working fine. I also want the 3rd column to sort in ASC order by default. This part isn't working, I cant get any of the columns to sort by default and can't figure out what's wrong with my syntax:</p>
  
  <pre><code>$(document).ready(function() {
  $(".table-sortable").dataTable({
      aaSorting: [],
      bPaginate: false,
      bFilter: false,
      bInfo: false,
      bSortable: true,
      bRetrieve: true,
      aoColumnDefs: [
          { "aTargets": [ 0 ], "bSortable": true },
          { "aTargets": [ 1 ], "bSortable": true },
          { "aTargets": [ 2 ], "asSorting": [ "asc" ], "bSortable": true },
          { "aTargets": [ 3 ], "bSortable": false }
      ]
  }); 
  });
  </code></pre>
