[Vuejs]-Materialize autocomplete not updating v-model of Vue app

Maybe this?

  mounted: function() {
    M.AutoInit();

    var options = {
      data: {
        "Emma Stone": null,
        "Batman": null,
        "Luke Skywalker": null,
      },

      onAutocomplete: function(res) {
        this.v-model_variable_name = res
      },
    };

    var elems = document.querySelectorAll(".autocomplete");
    var instances = M.Autocomplete.init(elems, options);

    console.log(instances);
  },

Or this answer in stackoverflow?

Did you found something since?
