BaseComponent can remove all event handlers

[literat]

WHEN (situation): when the component adds event handlers,
WHAT: I want it to be able to remove them,
WHY: because I need to dynamically create and remove components and I don't want to leave a mess behind.

Acceptance criteria
if I call the dispose() method, it will remove all event handlers of the component
Implementation notes (optional)
