JQuery DataTable passes parameter to ajax call to asp.net. Invalid JSON primitive

Question

Below is the java script code to populate my HTML table with server data, and I am using JQuery DataTables for this purpose.

function LoadData(result) {
$('#example').DataTable({
"ajax": {
   "dataType": 'json',
   "contentType": "application/json; charset=utf-8",
   "type": "POST",
   "url": "index.aspx/Risky",
   "data": function (d) {
    return JSON.stringify( d )
    //return JSON.stringify(result);
    // d.extra_search = result;      
    //"extra_search": result

   },
   "dataSrc": function (json) {
       return $.parseJSON(json.d);
   }
},
"columns": [
    { "data": "Prctice_Group_Risk_No" },
    { "data": "Practice_Group" },
    { "data": "Risk_Category" },
 ]
});
}

Below is my code for the description of the web method

[WebMethod]
[ScriptMethod]
public static string Risky()
{
  return JsonConvert.SerializeObject(riskList);
}

So far, his work is beautiful, my web method is being called, and my HTML table is populating.

But my problem is that I want to pass the result variable as a parameter to this ajax call so that my web method gets it and returns me certain data based on this parameter.
