Global callback does not call, am I doing something wrong?

[alisomay]

Here is the minimalized example about the case which confuses me.

slint::slint! {
    export global Logic {
        callback app_init();
    }

    export component App inherits Window {
        init => {
            debug("1");
            Logic.app_init();
        }
    }
}

fn main() {
    let app = App::new().unwrap();
    app.global::<Logic>().on_app_init(|| {
        // Not executed
        println!("2");
    });
    app.run().unwrap();
}

I'd expect to have

1
2

as the output but I have

1

am I missing something?

Thanks in advance 🙏

The thing is that the init is called as a result of App::new() before you have the chance to set the callback. That's why it doesn't work.
