MVC3 Ajax form submitting multiple times - ajax

Question

I am using Ajax Form in my page , I have couple of AJAX forms in the page one --(Customers.cshtml) , and the other comes as PARTIAL VIEW (_customers.cshtml). When I Submit the Partial View. This PARTIAL VIEW IS submitting multiple times**
I am using the following Ajax script in main page and also in Partial View
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")"
My code follows like this :
Customers.cshtml replaces the div tag with id="customers"
---------------------------------------------------------------------
<script src="#Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/json2.js")" type="text/javascript"></script>
#if (false)
{ <script src="~/Scripts/jquery-1.7.1-vsdoc.js" type="text/javascript"></script> }
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
#using (Ajax.BeginForm("Action1", "Controller1", new AjaxOptions() { InsertionMode = InsertionMode.Replace, UpdateTargetId = "customers" }))
{
#Html.AntiForgeryToken()
<input type="submit" class="t-button t-state-default"/>
}
<div id="customers"> </div>
<div id="Orders"></div>
<div id="customers> tag is replaced with a partial view which has another AJAX FORM
**_customers.cshtml replaces the div tag with id="orders"**
--------------------------------------------------------
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
#using (Ajax.BeginForm("Action2", "Controller1", new AjaxOptions() { InsertionMode = InsertionMode.Replace, UpdateTargetId = "Orders" }, new { id = "formupdate" }))
{
#Html.AntiForgeryToken()
<input type="submit" class="t-button t-state-default"/>
}
Now when I try to submit the **_customers.cshtml** , it is submitting more than once
<br/>
Controller
-----------------------------------------------
[HttpPost]
public ActionResult Action1()
{
return PartialView("_customers");
}
[HttpPost]
public ActionResult Action2()
{
return PartialView("_Shipping");
}
