Events are not firing

[ooo2003003v2]

It wont fires the alert that I set in beforeOpen

 <vue-clock-picker
                id="time-range-end"
                refs="timeRangeEnd"
                v-model="inspectionTimeRange.end"
                :beforeOpen="()=>{
                      alert();
                })"
              ></vue-clock-picker>

Because you wanna fire event as a prop.

try: @beforeOpen
