jquery - Change settings value on the fly?

Question

Is it possible to change jQuery DataTables settings value on fly. My problem is next,I need to change sAjaxSource on fly. Already tried something like this:

var oDefault = {
    "bServerSide": true,
    "bProcessing": true,
    "bJQueryUI": true,
    "bLengthChange": false,
    "bFilter": true,
    "iDisplayLength": 8,
    "sAjaxSource": "my.php?" + "idKat="+aData[3],
    "aaSorting": [[ 0, "asc" ],[ 3, "asc" ]],
    "sDom": '<"top"ir>t<"bottom"pf<"clear">',
    "sPaginationType": "full_numbers",
    "oLanguage": {
        "sUrl": "<?php echo $full_path_jezik_2;?>"
    },
    "aoColumns": [
        { "sName": "rb","sWidth": "15%", "sClass": "center","sType": "numeric" },
        { "sName": "chkZaBrisanje","sWidth": "20%", "sClass": "center", "bSortable":false },
        { "sName": "rbPrvaSlika","sWidth": "15%", "sClass": "center","bSortable":false  },
        { "sName": "nazivSlike","sWidth": "50%", "sClass": "center", "sSortDataType": "dom-text"  }
    ]
};

var oST = $.extend( true, {}, oDefault );
oST.sAjaxSource = "my.php?" + "idKat="+aData[3];

alert(oST.sAjaxSource);

if (typeof oTable == 'undefined') {
    oTable = $("#my-table").dataTable(oST);
}
else
{               
    oTable.fnDraw();
} 

My aData[3] is changed on click.

Have you tried

 oTable = $("#my-table").dataTable(oST);
 var oSettings = oTable.fnSettings();
 oSettings.sAjaxSource  = "new value";
