The call to `trigger` generates a [_CustomEvent_](https://developer.mozilla.org/docs/Web/Guide/Events/Creating_and_triggering_events)
of type `menu-loaded` and dispatches it on the component's DOM element
(`this.el`). The event bubbles and is cancelable. The parent component listening
to event `menu-loaded` will receive the payload in its `someMethod` handler
(in the `detail` property of the event), whenever the event is triggered.
The call to `trigger` generates an `OwlEvent`, a subclass of [_CustomEvent_](https://developer.mozilla.org/docs/Web/Guide/Events/Creating_and_triggering_events)
