Kendo Upload with complex obejct as data

Question

I've read this post but it doesn't seem to be working. Is there really no way to pass data or am I missing something?

C#

public async Task<HttpResponseMessage> ApiMethod(Person person) 
{
    //...do stuff
}

javascript

$("#files").kendoUpload({
    async: {
        saveUrl: 'www.api.com/controller/ApiMethod',
        autoUpload: true,
    },
    upload: function (e) {
        e.data = { 
            person: {
                FirstName: "First",
                LastName: "Last",
            },
        };
    },
});

When I check the Network tab in developer tools, I don't see any data being passed through.
