I want to use a internationalization option at my jQuery Mobile and jQuery webside. I tried to generate an example with the documentation on <http://i18next.com> but it seems I failed. Does anybody has experiences with i18next?

Here my example:

index.html:

```
<html>
  <head>
    <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1">
    <script src="jquery-mobile/jquery-1.6.4.min.js"       type="text/javascript"></script>
    <script src="jquery-mobile/jquery.mobile-1.0.min.js"  type="text/javascript"></script>
    <script src="js/i18next-1.5.6.min.js"                 type="text/javascript"></script>
    <script src="js/translation.js"                       type="text/javascript"></script>
  </head>
  <body>
    <div data-role="page" id="page">
    <div data-role="content">
      <div id="headline1" data-i18n="headline"></div>
        <table width="100%" border="0" id="menu1" class="menu">
          <tr id="surname">
            <td width="50%" data-i18n="menu.surname"></td>
            <td width="50%">&nbsp;</td>
          </tr>
          <tr id="firstName">
            <td width="50%" data-i18n="menu.firstName"></td>
            <td width="50%">&nbsp;</td>
          </tr>
        </table>
      </div>
    </div>
  </body>
</html>

```

Translation files:
/locales/de/translation.json

```
{
  "menu": {
    "surname": "Name:",
    "firstName": "Vorname:"
  },

  "headline": "Daten:",
  "headline_1": "Daten Allgemein:",
  "headline_2": "Daten Speziell:"
}

```

/locales/en/translation.json

/locales/dev/translation.json

```
{
  "menu": {
    "surname": "Name:",
    "firstName": "First Name:"
  },

  "headline": "Data:",
  "headline_1": "Daten Common:",
  "headline_2": "Daten Specific:"
}

```

/js/translation.js

```
$(document).ready(function(){
  language_complete = navigator.language.split("-");
  language = (language_complete[0]);
  console.log("Sprache (root): %s", language);

  i18n.init({ lng: language });
  i18n.init({ debug: true });
  $(".menu").i18n();
  $("headline").i18n();
});

```

The translation for the menu I get is "menu.name" instead of expected "Name:".
For the headline I get no translation but I expected "Data:" or "Daten:".

If i try the following direct call I get no translation: 
 i18n.t("menu.surname", { defaultValue: "Name:"});

Does anybody know what the problem is? Or does anybody has a working example that fits what I try to do?
