Ajax load issue with MVC Pager control

We have an MVC pager control on a view, when moving to a new page with the next, previous, or page number, the page loses all of its CSS. The pager ajax loads the view into the div it's sitting in. Here's the view, moving page to page fires the controller action correctly but when the view returns the CSS is gone. Any help is mucho appreciato

<%@ Control Language="VB" Inherits="System.Web.Mvc.ViewUserControl(Of PagedList(Of ClarifirePortal.PortalAnnouncement))" %>
<%@ Import Namespace="Webdiyer.WebControls.Mvc"  %>

<script type="text/javascript" >

    function gotoSearch() {

        window.location.href = '<%:URL.Action("Search","Home") %>';
    }

    function openDIV(divID) {

       var ele = document.getElementById(divID);

        if (ele.style.display == "block") {
            ele.style.display = "none";
          }
        else {
            ele.style.display = "block";
        }        
    }

</script>

It was necessary to add a script reference in my view to the unobtrusive ajax file, that fixed it
