Add a row after the selected row in jQuery dataTables

Question

DataTable is defined as

var oTable = $(\'#table1\').dataTable({
    \'aaData\': [
                 [\'John\', \'ABC\', \'$90000\'], [\'Doe\', \'XYZ\', \'$100000

Think you are too hasty to accept that you cant do what you want :) Of course it is possible, but it is hard to figure out under which circumstances. The question is not very specific. The following code inserts a new row just after the last row you have clicked :

var dataTable;
var options = {
    bSort: false,
    bPaginate: false
};

function initDataTable() {
  dataTable = $('#example').dataTable(options);
}

function attachClickHandler() {
    $("#example tbody tr").click(function(event) {
        var index=$(this).index();
        $("#insert").text('insert a row below the row you just clicked ('+index+')').attr('index',index).show();
    });
}

$("#insert").click(function() {
    var index=$(this).attr('index');
    var newRow = ''+
        'new'+
        'new'+
        'new'+
        'new'+
        'new' +
        '';
    dataTable.fnDestroy();
    $("#example tbody tr").eq(index).after(newRow);    
    initDataTable();
    attachClickHandler();
});

initDataTable();
attachClickHandler();

The idea is to insert the new row to the underlying DOM table, and then reinitialize dataTable when it is done. It works also by sorting, but for demonstration purposes I turn sorting off. As @scottysmalls mentions, dataTables is really sorting everything, so a new inserted row will immediately be sorted, and that would look like it was not inserted correct.
