Accessing Vue-data while in $ons.notification

    How can I retrieve from data while in this.$ons.notification.confirm callback?

    <script>
export default {
  name: 'groups',
  data () {
    return {
      myGroups: JSON.parse(localStorage.getItem("myGroups")),
    }
  },
  methods: {
    deleteGroup: function(groupId) {

      console.log(this.myGroups); // ****** OKE here ******

      this.$ons.notification.confirm('Are you sure?',
          { modifier: 'material',
            cancelable: true,
            title: 'Delete group?',
            buttonLabels: ['Yes', 'No'],
            callback: function(answer) {
                if (answer == 0) { //YES
                  console.log(this.myGroups) // ***** Undefined here ?? *****
                }
            }
          })
    }
}
</script>

    The above is probably not OnsenUI related and has something to do with scope/async.
    But doing it like this:

    $ons.notification.confirm('Are you sure?',
          { modifier: 'material',
            cancelable: true,
            title: 'Delete group?',
            buttonLabels: ['Yes', 'No']}
 ).then((response) => {
    console.log(this.myGroups) // ***** Works FINE !!! *****
  });

    as stated here: https://onsen.io/v2/api/vue/$ons.notification.html

    it works fine…

    @Bassie JavaScript issue: Use an arrow function instead. Normal functions create new contexts but arrow functions don’t.
