MVC RedirectToAction through ajax jQuery call in knockoutjs is not working

I am building a MVC3 web application and I am using knockoutjs. There are two views in the application. SetUpNewCompany and ManageAccount. To Set up a new company the user first enters the account number and clicks search. If the account number already exists the user can click on a button to go to the ManageAccount view. In the SetUpNewCompanyController I redirect using the RedirectToAction method. However, when the Index2 action in ManageAccount is executed the view is not displayed. If I type in the complete URL the view is displayed.

SetUpNewCompanyController.cs

[HttpPost]
 public RedirectToRouteResult RedirectToManageAccount(string accountNumber)
 {
        return RedirectToAction("Index2", new RouteValueDictionary(new {controller=
            "ManageAccount", companyId = "7e96b930-a786-44dd-8576-052ce608e38f" }));
 }

This above is called by the function below when a button is clicked

self.redirectToManageAccount = function () {
        var accountNumber = "7e96b930-a786-44dd-8576-052ce608e38f";
        $.ajax({
            type: "POST",
            url: "/SetUpNewCompany/RedirectToManageAccount",
            data: { accountNumber: accountNumber },
            success: function (data) {
            },
            error: function () {
            }
        });
 }

ManageAccountController.cs

public ActionResult Index2(String companyId)
    {
        var viewModel = new Models.Index();

        List<String> compList = new List<String>();
        compList.Add("MyCompany");

        List<String> usersList = new List<String>();
        usersList.Add("User1");

        viewModel.Users = usersList;
        viewModel.Companies = compList;
        viewModel.CompanyId = companyId;
        viewModel.Role = "Role1";

        return View("ManageAccount",viewModel);
    }

The URL that is generated is

http://localhost:53897/ManageAccount/Index2?companyId=7e96b930-a786-44dd-8576-
052ce608e38f

The console window in Firebug shows

GET http://localhost:53897/ManageAccount/Index2?companyId=7e96b930-a786-44dd-8576-
052ce608e38f 200 OK and the spinner keeps spinng

Also, how do I get the URL below instead of the one with querystring

http://localhost:53897/ManageAccount/Index2/7e96b930-a786-44dd-8576-052ce608e38f
