just my two pennies: i hate to do any data manipulation in C
so for handling multiple event handlers i does the same in Lua:

handlers = {}
function add_handler(event,handler)
  handlers[event] = append (handlers[event] or {},  handler)
end

add_handler("event1",
  function(obj)
  -- event1 handler
  end)

-- Called from C in case of event
function event1(obj)
  for _,v in ipairs(handlers.event1 or {})
    v(obj)
  end
end
