To Reproduce Steps to reproduce the behavior:

• Code/Link to Repo:

class QueryState(BaseState):
    label: str
    labels: List[str] = []
    nodes: List[str] = api.get_nodes()

    def add_label(self) -> None:
        if not self.label:
            return
        self.labels += [self.label]

    def remove_label(self, label: str) -> None:
        self.labels = [_label for _label in self.labels if _label != label]

    def reset_label(self) -> None:
        self.label = ""

    def reset_labels(self) -> None:
        self.labels = []

    def reset(self):
        return [self.reset_labels(), self.refresh_nodes()]

    def refresh_nodes(self) -> None:
        self.nodes = api.get_nodes(self.labels)

pc.box(
    pc.foreach(
        QueryState.labels,
        lambda label: pc.hstack(
            pc.box(
                pc.text(label),
                width="fit-content",
                margin="0.5rem",
                margin_right="0rem",
                padding="0.5rem",
                display="inline-block",
                bg=style.get_color("gray", 50),
                font_size="sm",
            ),
            pc.icon(
                tag="CloseIcon",
                margin="0",
                pading="0",
                color=style.get_color("gray", 300),
                font_size="0.5rem",
                _hover={
                    "color": "#000000",
                    "cursor": "pointer",
                },
                on_click=[
                    lambda: QueryState.remove_label(label),
                    QueryState.refresh_node,
                ],
            ),
        ),
    ),
    min_height="50px",
    padding="1rem",
)

Expected behavior A clear and concise description of what you expected to happen.

Even if click_on contains a lambda inside the chain of event triggers, there should be no errors.

on_click=[
    lambda: QueryState.remove_label(label),
    QueryState.refresh_node,
]

is this intended? Am I misunderstanding how to use it?

Are there any other possible ways now to use the above?

Might be related to #317

The error is the same as when using partial in event chain so it's probably the same problem.

Yeah I think we need to add support for this, will prioritize even chain issues
