Ember.js ember-plupload drag&drop

I want to create a drag & drop upload file ember.js app, I'm trying to use ember-plupload, but I can't make the plupload work, here is my code:

  <div class="dropzone" id=>
    
      
        Drop to upload
      
        Invalid
      
    
      Uploading  files. (%)
    
      <h4>Upload Images</h4>
      <p>
        
          Drag and drop images onto this area to upload them or
        
        <a id="upload-image">Add an Image.</a>
      </p>
    
  </div>

It's the sample template from plupload. And a route:

import Ember from "ember";

const get = Ember.get;
const set = Ember.set;

export default Ember.Route.extend({

  actions: {
    uploadImage: function (file) {
      var product = this.modelFor('product');
      var image = this.store.createRecord('image', {
        product: product,
        filename: get(file, 'name'),
        filesize: get(file, 'size')
      });

      file.read().then(function (url) {
        if (get(image, 'url') == null) {
          set(image, 'url', url);
        }
      });

      file.upload('/api/images/upload').then(function (response) {
        set(image, 'url', response.headers.Location);
        return image.save();
      }, function () {
        image.rollback();
      });
    }
  }
});

Sample again. Finally there is the result, the page

Upload Images

Drag and drop images onto this area to upload them or Add an Image.

But I can't drag anything onto it. And a firebug log:
