@Override
    public boolean onJsConfirm(WebView view, String url, String message, JsResult result) {
      selendroidWCC.onJsConfirm(view, url, message, result);
      return WCC.onJsConfirm(view, url, message, result);
    }
Unconventional way of adding a Javascript interface but the main reason why I took this way
is that it is working stable compared to the webview.addJavascriptInterface way.
