Applying dragula to list in Meteor

[mazing]

In Meteor, I have a template

<template name="tasks">
  <ul class="list-group">
    {{#each tasks}}
      {{> task}}
    {{/each}}
  </ul>
</template>

in which I initialize dragula with

Template.tasks.onRendered( function () {
  dragula( [ this.find( 'ul' ) ] );
} );

It gets initialized but when I am dragging an element, I get the errors

Uncaught TypeError: Cannot read property 'appendChild' of null  [dragula.js:463]
Uncaught TypeError: Cannot read property 'className' of null  [dragula.js:28]

I am loading dragula.js with meteor-bower.

What is wrong?
