ent type will be removed.
If eventType is excluded, ALL listeners will be removed from the component.
Alternatively you can use <code>off</code> to remove listeners that were added to other
elements or components using <code>myComponent.on(otherComponent...</code>.
In this case both the event type and listener function are REQUIRED.</p>
