Datepicker doesn't work

Expected behavior The datepicker should change the date on confirm

Actual behavior There is no date selected on the datepicker

I want to use Datepicker to allow my customer to find a foodtruck where there is. So every time I choose a new date, it should requery the foodtrucks available on this date. But actually, it's not working, there is note date selected and no new query on date change.

Here is my datepicker:

<MDBDatepicker
          className="kr-datepicker"
          monthsFull={monthsFull}
          monthsShort={monthsShort}
          weekdaysFull={weekdaysFull}
          weekdaysShort={weekdaysShort}
          weekdaysNarrow={weekdaysNarrow}
          cancelBtnText="Annuler"
          clearBtnText="Effacer"
          format="dd/mm/yyyy"
          min={new Date(year, month - 1, day - 1)}
          value={date}
          inputToggle
          inputStyle={{ width: "8rem" }}
          labelText="Date"
          title="Seul les dates avec des foodtrucks sont sélectionnable"
          setValue={setDate}
          // onChange={handleDatepicker}
          //Filter to show only date with reservations
          filter={function filterFunction(date) {
            const formatDate = formatDateIsoToServer(date);
            if (
              datesWithReservations &&
              datesWithReservations.includes(formatDate)
            ) {
              return true;
            }
            return false;
          }}
        />

Is it right to setValue ?
