I want to pass multiple parameters from Url.Action, Here is code in view

 window.location.href = @Url.Action(ABC, XYZ, new { @A= ViewBag.A , @B =  ViewBag.B });

And this is my Method in Controller XYZ

 public ActionResult ABC(string A, string B)

 {

    // Some Code

 }

I always get values in first parameter only and 2nd one is always null. Either if I but B first. 2nd one is always null.
VIEW is basically under JavaScript function.
Here is the URL: http://localhost/CargoMainSite/XYZ/ABC?A=1&B=2
Please note there is some extra text between Parameter one and Parameter two, that is amp; if I explicitly removes it. It works fine and get proper values.
