I solved the problem by using the technique provided in the answer in this question:

ASP.NET MVC: Controlling serialization of property names with JsonResult

Here is the class I made:

/// 

/// Similiar to , with
/// the exception that the  attributes are
/// respected.
/// 
/// 
/// Based on the excellent stackoverflow answer:
/// https://stackoverflow.com/a/263416/1039947
/// 
public class JsonDataContractActionResult : ActionResult
{
    /// 

    /// Initializes a new instance of the class.
    /// 
    /// Data to parse.
    public JsonDataContractActionResult(Object data)
    {
        Data = data;
    }

    /// 

    /// Gets or sets the data.
    /// 
    public Object Data { get; private set; }

    /// 

    /// Enables processing of the result of an action method by a 
    /// custom type that inherits from the ActionResult class. 
    /// 
    /// The controller context.
    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
            throw new ArgumentNullException("context");

        var serializer = new DataContractJsonSerializer(Data.GetType());

        string output;
        using (var ms = new MemoryStream())
        {
            serializer.WriteObject(ms, Data);
            output = Encoding.UTF8.GetString(ms.ToArray());
        }

        context.HttpContext.Response.ContentType = "application/json";
        context.HttpContext.Response.Write(output);
    }
}

Usage:

    public ActionResult TestFunction()
    {
        var testObject = new TestClass();
        return new JsonDataContractActionResult(testObject);
    }

I also had to modify the initial class:

// -- The DataContract property was added --
[DataContract]
public class JsonTreeNode
{
    [DataMember(Name = "title")]
    public string Title { get; set; }

    [DataMember(Name = "isFolder")]
    public bool IsFolder { get; set; }

    [DataMember(Name = "key")]
    public string Key { get; set; }

    [DataMember(Name = "children")]
    public IEnumerable Children { get; set; }

    [DataMember(Name = "select")]
    public bool SelectedOnInit { get; set; }
}
