I have a view(content), and i want pass data from this view to controller, i was used $.ajax but it not working.

My controller.

public class SignUpController : UmbracoApiController
{   
    [HttpPost]
    public string  UpLoad(string name)
    {
        return "Hello" + name;
    }
}

My view

$('#upload').click(function () {
                $.ajax({
                    url: "umbraco/api/SignUp/UpLoad",
                    data: {
                        name: "Trung"
                    },
                    type: "Post",
                    datatype: "Json",
                    success: function () {
                        alert(data);
                    }
                });
            });
