Hi everyone, using javasript I managed to do an auto completion textbox. It worked in the testing app, but when I used it for the existing application, the controller method is always getting a null value. I guess the javascript function is returning a Null value. Does anyone have an idea on this? Thanks in advance!!!

code :

{
//in the  Homecontroller
           
        public JsonResult AutocompleteSuggestions(string serchtext)
        {
            var suggestions = selectEmployees.getEmployeeSuggestedNumbers(serchtext);
            return Json(suggestions, JsonRequestBehavior.AllowGet);
        }

//searchtext getting Null values from the View

<script src="<%: Url.Content("~/Scripts/jquery-1.4.4.min.js")%>" type="text/javascript"></script>
    <script src="<%: Url.Content("~/Scripts/jquery-ui.min.js")%>" type="text/javascript"></script>


      //in the index.aspx


<h3 class="searchlabel">Search</h3>

<form1  runat="server" action = "" method="post">
 <input id="searchTerm" name="searchTerm" type="text" />&nbsp;

     <script type="text/javascript">
         $(function () {
             $("#searchTerm").autocomplete({
                 source: "/Home/AutocompleteSuggestions",
                 minLength: 1,
                 select: function (event, ol) {
                     if (ol.item) {
                         $("#searchTerm").val(ol.item.value);
                         $("form1").submit();
                     }
                 }
             });
         });
    </script>

   <%-- <% Html.RenderPartial("~/Views/Home/Search.ascx"); %>   --%>
