MVC - Postback on clicking a radio button

If you had radio buttons like:

 type="radio" name="sex" value="male" /> Male
 />
 type="radio" name="sex" value="female" /> Female

You could add script (assuming you can use jQuery) on the page like:

Assuming you have an action method in the same controller as the one that generated your view:

public class YourController : Controller
{
    public ActionResult sex(string sex)
    {
        // do something awesome
        return Json(new { someValue = "testing!" });
    }
}
