dataTables Change Data for ajax call
<p>I'm using the following function to load a DataTables table with data from the server. I would like to reload the table with different parameters on a click event only i cant work out how to do this. If i call reload it just reloads with the original parameters if i reinitialise the whole table it throws an error as the table already exists.</p>

<p>I have been looking into fnServerParams but cant work out if it would help or not.</p>

<p>If anyone can point me in the correct direction that would be great.</p>

<pre><code>function LoadRiskProfileModalTable(userId, teamId, riskProfileClass) {

var params = {
    userId: userId,
    teamId: teamId,
    riskProfileClass: riskProfileClass
};

var data = JSON.stringify(params);
//if (!$.fn.DataTable.isDataTable("#riskProfileTable")) {

    var table = $("#riskProfileTable").DataTable({
        "bProcessing": true,
        "sAjaxSource": "WFMHome.aspx/GetRiskProfileDrillThroughDatatable",
        "fnServerData": function (sSource, aoData, fnCallback) {
            //aoData.push(JSON.stringify(params));
            $.ajax({
                "dataType": 'json',
                "contentType": "application/json; charset=utf-8",
                "type": "POST",
                "url": sSource,

                "success": function (msg) {
                    var json = jQuery.parseJSON(msg.d);
                    fnCallback(json);
                    $("#riskProfileTable").show("fast", function () { $('#riskProfileTableLoading').hide("fast") });
                },
                error: function (xhr, textStatus, error) {
                    if (typeof console == "object") {
                        appendAlert("errorAlertPlaceholder", xhr.responseText, 1, "danger");
                        console.log(xhr.status + "," + xhr.responseText + "," + textStatus + "," + error);
                    }
                }
            });
        },
        "columns": [
