body: <p>I am working on some Backbone based project where i am using i18next for locales.</p>
  
  <p>Following is my app.js code:</p>
  
  <pre><code>    /*
      This file is used to initialize your application.
  */
  require(['i18n','application','handlebars_Helpers'], function(i18n, Application) {
  
      i18n.init({
          lng: 'en',
          debug: true,
          fallbackLng: false,
          load:'unspecific',
          resGetPath: "locales/__lng__/__ns__.json",
          ns: {
              namespaces: ['translation']
          }
      });
  
      (new Application()).initialize();
  });
  </code></pre>
  
  <p>Translation file:</p>
  
  <pre><code>{
      "loginModule": {
          "signin": "Sign In"
      }
  }
  </code></pre>
  
  <p>Following is my helper file:</p>
  
  <pre><code>/**
   * Set of generic handlebars helpers
   */
  define(['i18n'], function(i18n) {
      /**
       * This helper provides i18Next in templates
       *
       *
       * Usage: span {{t "my.key" }}
       */
      Handlebars.registerHelper('t', function(i18n_key) {
          var result = i18n.t(i18n_key);
          return new Handlebars.SafeString(result);
      });
  
      return Handlebars;
  
  });
  </code></pre>
  
  <p>When i am loading my page through localhost it shows me following message in console:</p>
  
  <pre><code>currentLng set to: en i18n.js:490
