Clock click toggle to display seconds

[omnigenous]

const clock = Variable(('CLOCK'), {
  poll: [1000, 'date "%H:%M"' ]
})

const Clock = Widget.ToggleButton({
  class_name: 'clock',
  child: Widget.Label({
    label: clock.bind()
  }),
  onToggled: ({ active }) => {
    print(`isActive: ${active}`)
  }
})

Not sure how I can change Clock.child.label inside onToggled
