  You need to use a callback function such as fnCreatedCell or fnDrawCallback to add the attributes you want to the DOM elements.

  In the fnRender I return a div to which I can then set the title - I can then use (for my title value) any field from my passed-in oObj.
  Ex: In the code below, I display in the table cell a short string repesenting a date (actually, only day and month) while in the title (aka tooltip for that cell), I display the full date and time including timezone, converted from the json as serialized by mvc (thus the extra code to read that date):
  [code]
  var otbl = $('#someTable').dataTable({
  "sAjaxSource": someUrl,
  "fnServerData": function (url, data, callback) {
  $.ajax({
  "url": url,
  "data": data,
  "success": callback,
  "contentType": "application/x-www-form-urlencoded; charset=utf-8",
  "dataType": "json",
  "type": "POST",
  "cache": false,
  "timeout": 60000,
  "error": function (jqXHR, textStatus, errorThrown) {
  if (otbl != undefined)
  otbl.fnProcessingIndicator(false);
  if (textStatus === "timeout") {
  alert("Downloading data has timeout. ");
  } else {
  alert("Downloading data has failed. Error: " + textStatus);
  }
  }
  });
  },
  "sDom": 'ritS',
  "aoColumns": [{ "mDataProp": "LogDateDisplay", "fnRender": function (oObj) {
  return '' +
  oObj.aData.LogDateDisplay + ''; } }
  ],
  "bServerSide": true
  });
  [/code]
  where the code to parse the mvc json date is (and you can ignore it as not part of your question though):
  [code] new Date(parseInt(oObj.aData.LogDate.replace("/Date(", "").replace(")/", ""), 10))[/code]

  Looks good - thanks for sharing your solution with us. fnRender is certainly a good option if you want to build the whole HTML string dynamically - if you want to add the attribute to a node, then fnCreatedCell or fnCreatedRow are there to provide that option.
