Datatables ajaxSource load twice

arunkarthik92

Hi
I am using datatables 1.9 and my ajax source is called twice. But this occurs onlywhen the page loads for the first time. On any subsequent operations ajaxSource is called once.

oTable = $('#UserDetailsTable').dataTable({
"sPaginationType": "full_numbers",
"iDisplayLength": 25,
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": fetch_user_details_url + "/" + time_limit,
//"sDom": 'l<"crumb">rftip',
"fnServerData": function (sSource, aoData, fnCallback) {
/* Add filter data and graph selection query to send to the server before send */

        aoData.push({some json});
        $.getJSON( sSource, aoData, function (json) { 

        });
    },

    "aoColumnDefs": [ 
                        {
                            "fnRender" : function(oObj, sVal) {
                                var aData = oObj.aData;
                                var deviceTable = fnUserDeviceDetails(aData);
                                return '<a href="'+usersViewUrl+'/'+aData[8].split('@@')[0]+'">'+aData[0]+'</a> <div class="row_displayer">' + userDeviceCountsText + imageOpenUrl + '</div>' + deviceTable;
                            },
                            "aTargets": [0]
                        },
                        {
                            "fnRender" : function(oObj, sVal) {
                                var aData = oObj.aData;
                                return '<a href="'+surveysViewUrl+'/'+aData[8].split('@@')[1]+'">'+aData[1]+'</a>';
