MVC :: Loading Partial View Based On Html Radiobutton Selection?

I have two strongly Typed partial views (Developers list and Testers list) and the respective views are Developers.ascx and Testers.ascx Now I want to load one partial view based on the radiobutton selected.

How to read the value of the radiobutton option? if anyone can provide Code snippet or some guidelines.

Here is my parent Controller Code & View:

Parent Controller:

[HttpGet]
public ActionResult View IT People List(string type)
{
var developers = from d in itEntity.Developers select s; return View(developers);
}
Parent View:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Mvc.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<DataModel.Developers>>" %>
<asp:Content ID="Content2" ContentPlaceHolderID="cphHead" runat="server">
</asp:Content>
<asp:Content ID="Content1" ContentPlaceHolderID="cphContent" runat="server">
<h2>View All IT Dept List</h2>
<table>
<tr>
<td><label for="txType">Select List:</label> </td>
<td>
<%= Html.RadioButton("Type", 1, true)%> Developers <%= Html.RadioButton("Type", 2, false)%> Testers
</td>
</tr>
<tr>
<td colspan = 2>
<%Html.RenderPartial("Developers", Model);%>
</td>
</tr>
</table>
</asp:Content>
Two strongly Typed Controllers are:
[HttpGet]
public ActionResult Developers()
{
var developers = from d in itEntity.Developers select d; return View(developers);
}
[HttpGet]
public ActionResult Testers()
{
var testers = from t in itEntity.Testers select t; return View(testers);
}
