title: Angular 2 Dragula Model updating incorrectly
body: <p>Working with ng2-dragula. I'm looking to update the orderNumber for every item in a database using the new dropped order.</p>
  
  <pre><code>dragulaService.dropModel.subscribe((value) =&gt; {
    var drake = dragulaService.find('bag-orders').drake
    var models = drake.models
    console.log(models)
  })
  </code></pre>
  
  <p>The new model order that it returns does not reflect the order within the bag.</p>
  
  <p><strong>TL;DR:</strong> has anyone implemented reordering within a database onDrop with ng2-dragula?</p>
