How To Set Checkbox Checked From Ajax Response In Datatable?

I have ajax response code here:

var dataCompetence = jsonData.dataCompetence;
if(jsonData.success){                      
      $.gritter.removeAll(); 
      $.each(dataCompetence.split(","), function(i,e){
         $("#competence_list input[value='" + e + "']").prop("checked", true);
      });

dataCompetence has value 2,5. I want to set checked checkbox that has same data with dataCompetence.
I got dataCompetence result from this code:

if (row.find('input[type="checkbox"]').is(':checked')){
    var compid = [];
    $('input[type="checkbox"]:checked', competence_list.fnGetNodes()).each(function(i) {
       var tr = $(this).closest('tr');
       var rowData = competence_list.fnGetData(tr);
       compid.push(rowData[1]);
    });
    $('#competence').val(compid); 

How to set the checkbox from that data? Thanks
