Partially filled object appears completely null at controller after ajax post – Jquery ajax

I am trying to send a partially filled object to my controller through an Ajax post.

var child =
{
    Property1: 1,
    Property2: 'test',
};
$.ajax({
    url: '/MyController/AddNewTest',
    type: 'POST',
    data: {"MyObject": child},
    success: function (data) {
    //Do stuff
    },
    error: function (data) {
    //Do stuff
    }
});

Controller: 

[HttpPost]
public ActionResult AddNewTest(MyObject object)
{
//Do stuff
}

Object:

The object MyObject, has a lot of other properties, but in this case, I only need Property1 and Property2(I suspect that this may be the issue). Instead of sending two strings to my controller, I would prefer to pass this partially filled object, as this makes my life a bit easier down the road.

The problem is, that once the object arrives at my controller, everything inside the object is empty.

    Use below in the $.ajax

    contentType: 'application/json; charset=utf-8',

    due to missing the contentType it default takes

    'application/x-www-form-urlencoded; charset=UTF-8'

    So when you receive in controller everything inside the object is empty.

    Refer: https://api.jquery.com/jquery.ajax/

    Or Else Pass data as

    $("#btnsubmit").click(function (e) {   
        //Serialize the form datas.   
        var valdata = $("#friendform").serialize();   
        //to get alert popup   
        alert(valdata);   
        $.ajax({   
            url: "/Friend/AddFriend",   
            type: "POST",   
            dataType: 'json',   
            contentType: 'application/x-www-form-urlencoded; charset=UTF-8',   
            data: valdata   
        });   
    });
