Bugs related to how event chains works

[Lendemor]

Describe the bug Trying to use event chains, I ran into a couple problems:

To Reproduce Problems encountered:

1. partial work if I'm using a single event handler, but not with chain.

pc.button("Trigger", on_click=[partial(State.subevent1, var), State.subevent2])

2. In this case, the var that I passed to sub_event1 is a str, but the value become '"my value"' instead of "my value"

# in State
def event(self, var):
        return [self.subevent1(var), self.subevent2]

# in render
pc.button("Trigger", on_click=partial(State.event, "my value")

Expected behavior Chained Events trigger correctly
