language option in reCAPTCHA ASP.NET plugin

I'm using ASP.NET plugin for reCAPTCHA in my ASP.NET MVC application. Recaptcha assembly version is 1.0.4.0. Is there a way to set language to be used for RecaptchaControl?

    var captchaControl = new Recaptcha.RecaptchaControl
            {
                ID = "recaptcha",
                Theme = "blackglass",
                PublicKey = "public_key",
开发者_Go百科                PrivateKey = "private_key"
            };

This feature was not supported in v1.0.4.0. Please download the latest version and try again.

with the help of this article here is how I've done it. the key is editing the generated html at the end; replacing "RecaptchaOptions = {" with "RecaptchaOptions = { lang : 'supported_language_code',"

public static string GenerateCaptcha(this HtmlHelper helper)
{
    var captchaControl = new Recaptcha.RecaptchaControl
            {
                ID = "recaptcha",
                Theme = "clean",
                PublicKey = "public_key_here",
                PrivateKey = "private_key_here"
            };
    var htmlWriter = new HtmlTextWriter(new StringWriter());
    captchaControl.RenderControl(htmlWriter);
    var html = htmlWriter.InnerWriter.ToString();
    html = html.Replace("RecaptchaOptions = {", "RecaptchaOptions = { lang : 'tr', ");
    return html;
}
