Event start-selection not working

[matthbon]

In the documentation i see an event start-selection. It should emit the event when user clicks first date of range.

But nothing is happening when I add it.

<date-range-picker
          ref="picker"
          v-model="dateRange"
          :locale-data="{firstDay: 1, format: 'DD-MM-YYYY', daysOfWeek: moment.weekdaysMin(), monthNames: moment.monthsShort(),}"
          :ranges="false"
          :autoApply="true"
          :singleDatePicker="false"
          :timePicker="false"
          :timePicker24Hour="false"
          :showWeekNumbers="true"
          :showDropdowns="true"
          :min-date="minDate"
          :max-date="maxDate"
          @start-selection="startDateSelection($event)"
      >
        <div slot="input" class="form-input cursor-default select-bg" slot-scope="picker">
          {{ picker.startDate | date }} t/m {{ picker.endDate | date }}
        </div>
      </date-range-picker>
