How to test two or more asynchronous calls in a function?

How to test two or more asynchronous calls in a function?

Hi,
I am doing jquery Qunit testing in my application, i use only asynchronous ajax calls. In a function i use 2 ajax calls. To test the async calls i use start() and stop(). In the callback of every async call i use start() and in test case after function is called, i use stop().

Original method:
============
function MyOriginalMethod()
{
Ajax_Async('/Home/Index' , null, 'GET' , false, MyCallBack1 );
Ajax_Async('/Home/MyAction' , 'myName=ramesh', 'GET', false, MyCallBack2);
}
var MyCallBack1 =(function(){
var home= $('body').data('result');
$('#master_div').html(home);
start(); / / corresponding stop is in test case......
});

var MyCallBack2 =(function(){
var userAction= $('body').data('result');
$('#user_div').html(userAction);
start(); // corresponding stop is in test case......
});

//Async function
function Ajax_Async(restUrl, params, restType, cacheFlag, callback) {
    $.ajax({
        type: restType,
        async: true,     //To make a ASYNC call only... callback will be called after success
        url: RootUrl_ + restUrl,
        data: params,
        cache: cacheFlag, //To clear Cache since the datatype can be Json.For Json datatype by defualt cache is true      
        success: function (result) {
            $('body').data('result', result); //which is used in callback...
            new callback;
        },
        error: function (error) {
            alert(error);
        }
    });
}

Test method:
=========

function MyTestMethod()
{
test('MyOriginalMethod', function(){
MyOriginalMethod();
stop(); //start is in callback of async call
        });

test('Test the Values', function(){
ok($('#master_div').children().length > 0, 'Values present in Master div');
ok($('#user_div').children().length > 0, 'Values present in User div');
});
}

When both are tested independently they get passed, but when the function as a whole including both is tested it gets failed. It would be great somebody can help me on this..

Thanks in advance..
