Accordion - no such method 'internal' for accordion widget instance

[niksa88]

Hi,

Ember version: 2.18.0 and 3.7.1
Semantic-UI-Ember: 3.0.3

{{#ui-accordion class="styled"}}
    <div class="title">
        Semantic UI
    </div>
    <div class="content">
        Accordion Component
    </div>
    <div class="title">
        Accordion Two
    </div>
    <div class="content">
        Content Two
    </div>
{{/ui-accordion}}

Accordion is working but I have error in my console "no such method 'internal' for accordion widget instance"

Thanks
