ViewBag is null on the second page of PagedList in mvc application - asp.net-mvc

Question

I m stuck on this for a while now and will appreciate any help.
The value of ViewBag.SearchTerm is null when I click on the 2 item in the paged list. My List page is present in a partial view (_CentraladdrcdoQuery) as below
#using SFRS.GazMatching.Web.DAL
#model IPagedList<CentraladdrcdoQuery>
#using PagedList;
#using PagedList.Mvc;
<div id="results" class="col-md-10">
<div class="row">
<div class="col-md-4">
<table class="table pull-left table-condensed">
<tr>
<td>
#Html.DisplayNameFor(model => model.First().RecordId)
</td>
</tr>
</table>
</div>
<div class="col-md-4">
<table class="table pull-left table-condensed">
#foreach (var item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.RecordId)
</td>
</tr>
}
</table>
</div>
<br />
</div>
<div class="row">
<div class="col-md-4 clearfix">
#Html.PagedListPager(Model, page => Url.Action("Search", new { page, ViewBag.SearchTerm }), new PagedListRenderOptions
{
LinkToFirstPageFormat = "<<",
LinkToPreviousPageFormat = "prev",
LinkToNextPageFormat = "next",
LinkToLastPageFormat = ">>",
})
</div>
</div>
The main search view is
#model IPagedList<CentraladdrcdoQuery>
#{
SearchFormViewModel searchFormViewModel = new SearchFormViewModel();
}
#Html.Partial("_SearchForm",searchFormViewModel)
<h2>Search Results</h2>
#Html.Partial("_CentraladdrcdoQuery", Model)
and the Search Controller action is
public ActionResult Search(string searchTerm, int? page)
{
var centraladdrcdoQuerylst= GetCentraladdrcdoQueryData(searchTerm,page);
ViewBag.SourceList = GetSourceList();
ViewBag.SearhTerm = searchTerm;
return View(centraladdrcdoQuerylst);
}
