WebAPI, [FromBody] string, application/json, Error 415 (Unsupported Media Type)

I have a WebAPI project (c#) and i test it with my page (Index.cshtml):

<html>
<head>
...
</head>
<body>

    <script src="@Url.Content("~/Scripts/jquery-3.2.1.js")" type="text/javascript"></script>
    <script type="text/javascript">

    function GetData() {
        $.ajax({
            url: "http://localhost:0000/api/test/test/cox/Test",
            type: 'POST',
            dataType: 'json',
            data: JSON.stringify("Hello!!!"),
            crossDomain: true,
            processData: false,
            contentType: 'application/json, charset=utf-8',
            headers: { User: "test", Password: "test" },
            success: function (q, w, e) {
                alert(JSON.stringify(q));
            },
            error: function (q, w, e) {
                alert("error: " + w);
            }
        });
    }

</script>

<p>
    <button onclick="GetData()">GetData</button>
</p>

</body>
</html>

This page call my method:

[HttpPost]
[ResponseType(typeof(IEnumerable<СompositeType>))]
public HttpResponseMessage Test(string cox, [FromBody] string str)
{
   ...    
}

and i get the error: 415 "Unsupported Media Type". I read about this error and somebody is talking that contentType: 'application/json, charset=utf-8' will solve the problem. I know that attribute [FromBody] call to contentType: 'application/json' for transformation , but i don't undestand why i have the error 415.

I found a solution, but it is a little cheat. (I want to say: "Thank you!)", for the answers).

The first. I changed this:

 data: JSON.stringify({"str":"Hello!!!"}),
 contentType: 'application/json; charset=utf-8',

The second. I changed this:

[HttpPost]
[ResponseType(typeof(IEnumerable<СompositeType>))]
public HttpResponseMessage Test(string cox, [FromBody] Test str)
{
   ...    
}

The third. I added a new class:

public class Test
{
    public string str { set; get; }
}
