TreeView not working

[dradovic]

I've tried to use the TreeView component of the aurelia-syncfusion-bridge component (11.0.3) but I get the following warning on the console:

Possible Unhandled Promise Rejection: TypeError: jQuery(...)[this.controlName] is not a function at ejTreeView.createWidget (widget-base.js?9120:60) at ejTreeView.attached (widget-base.js?9120:151) at ejTreeView.descriptor.value [as attached] (decorators.js?6f1d:87) at Controller.attached (aurelia-templating.js?8628:3759) at View.attached (aurelia-templating.js?8628:1772) at ViewSlot.attached (aurelia-templating.js?8628:2130) at View.attached (aurelia-templating.js?8628:1777) at Controller.attached (aurelia-templating.js?8628:3763) at View.attached (aurelia-templating.js?8628:1772) at ViewSlot.attached (aurelia-templating.js?8628:2130)

And the tree view does not collapse or expand when clicking on the items.

This is how I tried to use it:

            <ul id="treeView" ej-tree-view="e-width:250">
                <li class="expanded">
                    Artwork
                    <ul>

                        </li>

                        </li>
                    </ul>
