This should do the trick.

$w.onReady(() => {
    $w("#myDataset").onReady(() => {
        $w('#repeater').forEachItem(($item, itemData) => {
            $w('#button').onClick(async () => {
                let newValue = itemData++
                $w("#myDataset").setFieldValue("number", newValue)
                await $w("#myDataset").save()
                $w("#myDataset").refresh()
            })
        })    
    })
}

I got this error:

Caused by: DatasetError: Operation (setFieldValue) not allowed on read-only dataset

Error: Operation (setFieldValue) not allowed on read-only dataset

You have unhandled error in async operation. Consider catching it and handling accordingly. DatasetError: Operation (setFieldValue) not allowed on read-only dataset

@charbel-keedy your dataset is set to read-only. Just change it to read and write.

How can i change it to read and write?

Click on the dataset element, select Settings, and you can find it in Mode:
