MVC 3 partialview popup problem

I have been trying to create a pop up window with some details gather from a partialview, but I was not able to do it.

I have followed this example, that is pretty clear, but did not work for me. MVC-pop up windows

I add my code, maybe someone can see better than me, why is not working.

Thanks in advance, Pablo.

This is the controller

    [HttpGet]
    [Authorize]
    public ActionResult _CustomerDetails(int idAddress)
    {
        using (CustomerAddressClient client = new CustomerAddressClient())
        {

            var address = client.CustomerAddress_Read(idAddress);

            ViewBag.CustomerAddress = address;
        }
        return PartialView();
    }

Then I have the view with this code

@Ajax.ActionLink("Open popup", "_CustomerDetails", new AjaxOptions { HttpMethod = "GET",       UpdateTargetId = "customerdetails2", InsertionMode = InsertionMode.Replace, OnSuccess = "openPopup" })

<div id="customerdetails2" ></div>

$(document).ready(function () {
    $("#customerdetails2").dialog({
        autoOpen: false,
        title: 'Title',
        width: 500,
        height: 'auto',
        modal: true
    });
});

function openPopup() {
    $("#customerdetails2").dialog("open");
}    

and the partial view is just a list of the customer details

<table style="width: 100%;" class="customerTable">
    <tr>
        <td>Address1</td> <td>@ViewBag.CustomerAddress.idAddress</td>
    </tr>
    <tr>
        <td>Address2</td><td>@ViewBag.CustomerAddress.Address2</td>
    </tr>
    <tr>
        <td>Address3</td><td>@ViewBag.CustomerAddress.Address3</td>
    </tr>
    <tr>
        <td>City</td><td>@ViewBag.CustomerAddress.City</td>
    </tr>
    <tr>
        <td>CompanyName</td><td>@ViewBag.CustomerAddress.CompanyName</td>
    </tr>
</Table>

Well,开发者_如何学Python the page keep on displaying in the same container, it won't display a popup.
