Can I call functions of component from parent?

[sqllyw]

Hi,

createApp({
        Counter,
        main_inc() {
            console.log('main click')
            Counter.inc()
        }
    }).mount()

can I call Counter.inc()?
here is the jsfiddle:https://jsfiddle.net/my3zsxgn/
I got :

Counter.inc is not a function

[solution-loisir]

Have you tried this.Counter.inc()?

thanks, it should have been this.Counter.inc(), but i still get:

this.Counter.inc is not a function

I think, a global state like this:

const counter = reactive({
            count: 0,
            inc() {
                this.count++
            }

        })

then I can have:

createApp({
        counter,
        main_inc() {
            console.log('main click')
            counter.inc()
        }
    }).mount()
