  What is `checkboxes` ? Is it an array? If so, you will need to loop over it and add each item at a time.

  Firts of all, thanks for the amazing library. Yesterdays problem is solved, here is the code:
  
  javascript
  [code]
  function generateDataTable(subject, checkboxesData) {
  
  var oTable = $('#datatable1').dataTable({
  "bProcessing": true,
  "bServerSide": true,
  "sAjaxSource": base_url() + '/' + 'ccreateexam/getQuestions',
  "fnServerParams": function(aoData) {
  
  aoData.push({"name": "subject", "value": subject});
  aoData.push({"name": "lessonsCount", "value": checkboxesData[0]});
  
  for(var i = 0; i < checkboxesData[0]; i++){
  aoData.push({"name": "selectedLessons[]", "value": checkboxesData[1][i]});
  }
  },
  "bJQueryUI": true,
  "sPaginationType": "full_numbers",
  "iDisplayStart ": 20,
  "fnInitComplete": function() {
  oTable.fnAdjustColumnSizing();
  },
  'fnServerData': function(sSource, aoData, fnCallback)
  {
  $.ajax
  ({
  'dataType': 'json',
  'type': 'POST',
  'url': sSource,
  'data': aoData,
  'success': fnCallback
  });
  }
  });
  }
  [/code]
  
  controller
  [code]
  public function getQuestions() {
  
  $subject = $this->input->post('subject');
  $lessonsCount = $this->input->post('lessonsCount');
  $selectedLessons = $this->input->post('selectedLessons');
  
  if (!empty($subject)) {
  echo $this->mcreateexam->getQuestionsForSubjectLessons($subject, $selectedLessons, $lessonsCount);
  } else {
  echo $this->mcreateexam->getQuestionsForAllSubjectsLessons($selectedLessons, $lessonsCount);
  }
  }
  [/code]
  
  Now we are stuck trying to add a checkbox for every row in the datatable in a new column with a paramatrized name or id. Now, we're adding the checkbox with specific id, but we need each checkbox to have a diferent name or id, so we can recover the checked status using javascript. Do you have any idea to help us? We thank you very much for your work and your time. Thanks.

  The mRender option might help here:
  
  [code]
  {
  mData: null,
  mRender: function ( data, type, row ) {
  return '';
  }
  }
  [/code]
  
  Assuming you have an `id` property in the row source object. Change to whatever you do have.

  Thank you Allan, we solved the problem using another code. We put an id in the name and we used this code:
  
  [code]
  $(document).ready(function() {
  $('#createExamButton').click(function() {
  
  var oTable = $('#datatable1').dataTable();
  var checkedQuestions = [];
  $("input:checked", oTable.fnGetNodes()).each(function(){
  var elemnt = this;
  checkedQuestions.push(elemnt.id);
  });
  alert(checkedQuestions);
  });
  });
  
  [/code]
