title: why render of jquery datatable does not execute?
body: <p>i have the following jquery <code>datatable</code> column <code>'DOB'</code> associated with a function</p>
  
  <pre><code>columns:[
  {
      'data': 'DOB',
      'visible': false,
      'render': function (jsonDate) {
          var date = new Date(parseInt(jsonDate.substr(6)));
          var month = date.getMonth() + 1;
          return month + '/' + date.getDate() + '/' + date.getFullYear();
       }
  },
  ]
  </code></pre>
  
  <p>but when i retrieve the value it retrieves as <code>Json</code> date <code>/Date(-133335000000)/</code> why this happens and how do i fix this?</p>
