c# - Javascript が Ext.Net で動作しない

Question

Ext.Net フレームワークで Asp.net を使用しています。また、JavaScript コードを使用する必要があります (ext.net コードではありません)。

Default.aspx ページ:

<asp:UpdatePanel runat="server">

            <ContentTemplate>
                <asp:Button runat="server" Text="tıkla" ID="btnGetir" OnClick="btnGetir_Click" />
............
............

Default.aspx.cs ページ:

 public void btnGetir_Click(object sender, EventArgs e)
    {


        String url = "http://blablablablabla:8080/MeramElektrik2/webresources/entities.layers/GetLayer/1004";

        String html_sonuc;
        WebResponse objResponse;
        WebRequest objRequest = HttpWebRequest.Create(url);
        objResponse = objRequest.GetResponse();

        using (StreamReader sr =
               new StreamReader(objResponse.GetResponseStream()))
        {
            html_sonuc = sr.ReadToEnd();
            sr.Close();
        }



        ////////////Script Çalıştırma Kodu///////////////////////////
        ScriptManager.RegisterStartupScript(
            this,
            this.GetType(),
            "deneme2",
            "deserialize('" + html_sonuc + "');",
            true);
        /////////////////////////////////////////////////////////////
            txtScript.Text = html_sonuc;
    }

OpenLayerUsers.js ページ:

function deserialize(html_sonuc) { //GEOJSON I, ÇİZİLMİŞ ŞEKLE DÖNÜŞTÜRÜYOR


//var element = document.getElementById('txtScript');
var features = geojson.read(html_sonuc);
//var features = json.read(element.value);
var bounds;

if (features) {
    if (features.constructor != Array) {
        features = [features];
    }
    for (var i = 0; i < features.length; ++i) {
        if (!bounds) {
            bounds = features[i].geometry.getBounds();
        } else {
            bounds.extend(features[i].geometry.getBounds());
        }

    }
    vectors.addFeatures(features);
    map.zoomToExtent(bounds);
    var plural = (features.length > 1) ? 's' : '';
   //element.value = features.length + ' feature' + plural + ' added'
} else {
  //element.value = 'Bad input';
}

}

結果、デシリアライズ (html_sonuc) 関数が機能しません。
