Integration issues with Google Transliteration for fckeditor

Hi I'm trying to integrate Google Transliteration code to fckeditor.

The following is my code

function FCKeditor_OnComplete( editorInstance ){
        var options = {
          sourceLanguage: 'en',
          destinationLanguage: ['ta','hi','kn','ml','te'],
          shortcutKey: 'ctrl+g',
          transliterationEnabled: true
        };
   var googleControl =
               new google.elements.transliteration.TransliterationControl(options);
   alert("Hi in here"+googleControl )
        var ids = ["post_title",FCKeditorAPI.GetInstance('post__body_editor')];        
        googleControl.makeTransliteratable(ids);
}

But the google transliteration works for "post_title" which is a plain text box but it is not working for fckeditor textarea.
Please help. i tried giving just the textarea name in ids but even that did not help.
