MVC，Jquery和Ajax-控制器中具有空参数的JSON

Question

I have a problem with passing object with properties into controller.
Both are always null.
In console.log passed data looks fine. Where I made a mistake?
I looked into other solutions and nothing pushed me to the correct way...

C#, MVC5, Jquery 2.1.1

Controller:

public class Position  
{  
string intnew { get; set; }  
string intlast { get; set; }  
}

Action:

 [HttpPost]
    public ActionResult change(Position position)
    {
    return Json(new { result = "" });
    }

And View:

var pos = new Object;
pos.intnew = '22';
pos.intlast = '11';

$.ajax({
url: '/szkolenia/change',
contentType: 'application/json; charset=utf-8',
datatype: 'json',
data: JSON.stringify({ position: pos }),
type: "POST",
success: function (_infoLogs) {
console.log(JSON.stringify({ position: pos }));
}
});

Your view model Properties must be Public !

public class Position  
{  
  public string intnew { get; set; }  
  public string intlast { get; set; }  
}

I suggest the first word of the Properties be uppercase.
