title: How to access ember helper from controller?
body: <p>I have a ember helper for string internalization. When accessing helper file from ember controller I got <code>variable</code> undefined error. </p>
  
  <p><strong>t-18n.js</strong></p>
  
  <pre><code>import Ember from 'ember';
  
  var i18nData = {
  "dashboard": "Dashboard",
  
  };
  
  export function tI18n(params/*, hash*/) {
  var value = i18nData[params];
  if(value) {
  return value;
  }
  return params;
  }
  
  export default Ember.Handlebars.makeBoundHelper(tI18n);
  </code></pre>
  
  <p><strong>Ember Controller</strong></p>
  
  <pre><code>    import i18n from 'osmizer-client/helpers/t-i18n'
      export default Ember.Controller.extend({
  actions: {
  get: function() {
  i18n.tI18n('dashboard')
  }
  }
  });
  </code></pre>
  
  <p>I got this error "<strong>i18n.default.tI18n is not a function TypeError: i18n.default.tI18n is not a function</strong>".  Please help me to solve this issue.</p>
