VsSelect doesn't change when I change the array

[rangeldor]

If I try to change the initial array, he doesn't change the childOptions, because of this he doesn't set label if the actual length array is bigger than the last length array.

If someone passes by, add a key to the select

          <vs-select
            label="Ville"
            v-model="cityChoice"
            :loading="cityLoading"
            :disabled="cityLoading"
            :key="cities.length" <!-- Add a key in connection with the options table -->
          >
            <vs-option
              v-for="(city, index) in cities"
              :key="index"
              :label="city.city.toString()"
              :value="city.city.toString()"
            >
              {{ city.city }}
            </vs-option>
          </vs-select>
