Trigger fnReorderCallback without reordering the table.

I need to call fnReorderCallback without reordering the table while outside (after) the dataTable() option configuration and initializaion.

Example:

I config and init table here...

var oTable = $(selector).dataTable({
    'sDom': 'Rfrtlip',
    'oColReorder': {
        'iFixedColumns': 2,
        'iFixedColumnsRight': 1,
        'fnReorderCallback': function(){
            var variableX = this.fnOrder();
            /* Some set of instructions here */
        }
    }, ... });

then I want to call fnReorderCallback somewhere after this snippet or at least, to be able to access variableX.

Is this possible in any way?

Thanks in advance.

Best,
H.
