ASP.NET MVC autopostback drop down not working

Question

With the following code:

<script type="text/javascript" src="../../Scripts/jquery-1.4.1.js" />
<script type="text/javascript">
    $(function () {
        $('#selectOptions').change(function () {
            $(this).parents('form').submit();
        });
    });
</script>

...

    <% using (Html.BeginForm("PostedValue", "Home"))
   { %>

<%: Html.DropDownList("selectOptions", new List<SelectListItem> 
                                 { new SelectListItem{ Text="1",  Value="1"},  
                                   new SelectListItem{ Text="2",  Value="2"},  
                                   new SelectListItem{ Text="3",  Value="3"}},
                                 "Select List")%>
<%} %>
</div> </body>
</html>

What am I doing wrong?

Answer 1

when I do the following it works

{ new SelectListItem{ Text="1", Value="1"}, new SelectListItem{ Text="2", Value="2"}, new SelectListItem{ Text="3", Value="3"}}, "Select List", **new { onchange = "$(this).parents('form').submit()"** })%>

I am wondering why $function() is not working..
