Dropped cloned Elements are getting synced about angular-dragdrop HOT 3 CLOSED

I found out a dirty way to make the cloning stop .
the problem is that the draggable items have the same ng-model

<li data-drag="true" class="col-lg-4" ng-model="emptyCol" jqyoui-draggable="{ animate:true , placeholder : 'keep' } "><a href="#">{{emptyCol.content}}</a></li>

I was able to workaround the issue by changing the ng-model each time an item is dropped in the playground

$scope.dropped = function  () {
$scope.emptyCol = {
      lg : 4 ,
      md : 6 ,
      sm : 6 ,
      xs : 6 ,
      content : 'Col 4'
    } ;
  }

Is there a better way to solve this ?

I did not understand the steps to follow from your first comment.

It was not an issue with angular drag-drop .
This is was the core issue was with the keys in ng-repeat
