changing language on application page

Question

I am using following code to change the language of HTML form on application page:

 <asp:Content ID="PageHead" ContentPlaceHolderID="PlaceHolderAdditionalPageHead" runat="server">

        <script type="text/javascript" src="/_layouts/SP.Core.js"></script>
        <script type="text/javascript" src="/_layouts/SP.Debug.js"></script>
        <script type="text/javascript" src="/_layouts/SP.Runtime.Debug.js"></script>

<script type="text/javascript">

    function ChangeLanguage(value) {
    var today = new Date();
    var oneYear = new Date(today.getTime() + 365 * 24 * 60 * 60 * 1000);
    var url = window.location.href;
    document.cookie = "lcid=" + value + ";path=/;expires=" + oneYear.toGMTString();
    window.location.href = url;
}

</script>
</asp:Content>

<asp:Content ID="Main" ContentPlaceHolderID="PlaceHolderMain" runat="server">
<form>
// My Html form is here.. with 3 input type text and one input type submit button

<a href="#" onclick="javascript:ChangeLanguage(1053);">swedish</a>
<a href="javascript:ChangeLanguage(1033)">english</a>
</form>
</asp:Content>

When i click on any of the hyperlinks above, nothing happened. I could not understand, what is wrong? I am using two types of links, but neither works
