Active checkbox when row selection already selected

My checkbox does not work when I have selected row table.

This is my row selection.

$('#mainTable tbody').on( 'click', 'tr', function () {
   $(this).toggleClass('selected');
   });

I have included handler for checkbox, but no luck.

"rowCallback": function(row, data, dataIndex){
         var rowId = data[0];

         if($.inArray(rowId, rows_selected) !== -1){
            $(row).find('input[type="checkbox"]').prop('checked', true);
            $(row).addClass('selected');
         }
      }
