Toaster Component - onDismiss () cannot find other methods

[jondiscipulo]

I am new to Quasar and utilizing the Toaster component:

  Toast.create.negative({
    html: 'Sorry, no user with that PIN code!',
    timeout: 2000,
    button: {
      handler () {
        // Specify what to do when button is clicked/tapped
      }
    },
    vm: {
      // VueModel for the Toast
    },
    onDismiss () {
      this.reset()
    }
  })

The function reset() is inside the methods object but onDismiss() seems unable to call it.
