feat: charjs style button trigger (#743)

# PR Checklist
- [ ] Have you checked if it works normally in all models? *Ignore this
if it doesn't use models.*
- [ ] Have you checked if it works normally in all web, local, and node
hosted versions? If it doesn't, have you blocked it in those versions?
- [ ] Have you added type definitions?

# Description
This pull request reintroduces charJS style button event previously
deprecated and removed, using luaEngine. This implementation diverges
from current style by passing attribute data as parameters rather than
function names.
