NULL controller parameter when using jQuery POST and ASP.NET MVC

Question

I have no problem processing jQuery GET requests in the controller, however I cannot get the form data in POST. Customer Fragment

$.post(url,{name:"John"},function(result){ 
    //process result
});

in combination with a controller,

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Save(string name)
{
    return Json("Success!");
}

will result in a NULL value for the name parameter when checking inside the action method, whereas I expected the name to be mapped to the method parameter. Also all other objects (Request.Form), etc. In this context, it seems NULL. I can do this with help $.get, but I think I should perform any side effect operations with POST. I am using ASP.NET MVC 1.0, jQuery 1.2.6 and Internet Explorer 7.

Thanks!
