I have the following issue: I am working on a vue.js openlayer map project. In my mounted() section I have an event handler which listens to the moving of features on the map. The new coordinates are well displayed in the console.log inside my event listener. Now, I would like to display the new coordinate in a vuetify v-text-field with v-model and later store in the vuex store. My problem is that the coordinate data assigned to this.coordinate inside the event listener is not available inside vuetify v-text-field. I spent several ours trying lots of different things. Despite dozens of searches on the web I did not come across a solution.
Any hints are welcomed.

Below the skeleton of the code:

<script>

export default {
  data() {
    return {
      coordinates: [0,0]
    }
  },

  mounted() {

    [...]

    selectedFeature.on('add', function(event) {
    
      // now we create an listener on change events 
      var feature = event.element;
      feature.on('change', function(event){
        let waypFeature = event.target.clone();
        let waypCoord = waypFeature.getGeometry().transform('EPSG:3857', 'EPSG:4326').getCoordinates();
        
        console.log("selectedFeature(change) / Coordinates waypCoord: %s/%s", waypCoord[0], waypCoord[1])

        this.coordinates
        /* I search for a a way to write the array waypCoord into the array test defined in data 
           (ultimately I need to write array into the vuex store) */
      })
    })

    // setup map
    const map = new Map({
      layers: layer,
      target: 'map',
      view: view,
    });
  },

}
</script>
