Confirm delete on tabletools?

Heya, so ive got a ajax delete command tied into an ajax button and am trying to implement a confirm window on it, so the user clicks delete and it pops up asking them to confirm they want to delete it:

{
 "sExtends": "ajax",
 "bSelectedOnly": "true",
 "sButtonText": "Delete Selected",
 "mColumns": [0],
 "bHeader": false,
 "sAjaxUrl": "dataTable/delete/cmsGroup", 

 "fnAjaxComplete": function ( XMLHttpRequest, textStatus ) {
$('tr.DTTT_selected').remove();
 }//delete button
},

now i hand wrote it out using a function call, but its MUCH more complex then the simple button is:

{
"sExtends": "text",
"sButtonText": "Delete",
"fnClick": function(nButton, oConfig, nRow){
if (confirm('Are you sure want to delete this record?')) {
var list = $('tr.DTTT_selected > td.sorting_1 > a').map(function () {
return this.text;
}).get().join(",");
$.ajax({
type: "POST",
	url: "dataTable/delete/cmsGroup",  
	data:   'tableData='+ list,  
	success: function(result) {  
	alert("Entry Deleted");
	$('tr.DTTT_selected').remove();
	}});
	}}},

Anyone know how to tack that confirm onto the regular tabletools method?
