RTC weakup interrupt does not work

I have used CubeMx to generate code for stm32f407
Set RTC internal weakup
and enabled the NVIC

but the  RTC_WKUP_IRQHandler() never got called!

code:
/* RTC init function */
void MX_RTC_Init(void)
{


  RTC_TimeTypeDef sTime;
  RTC_DateTypeDef sDate;
  RTC_AlarmTypeDef sAlarm;


    /**Initialize RTC and set the Time and Date 
    */
  hrtc.Instance = RTC;
  hrtc.Init.HourFormat = RTC_HOURFORMAT_24;
  hrtc.Init.AsynchPrediv = 127;
  hrtc.Init.SynchPrediv = 255;
  hrtc.Init.OutPut = RTC_OUTPUT_DISABLE;
  hrtc.Init.OutPutPolarity = RTC_OUTPUT_POLARITY_HIGH;
  hrtc.Init.OutPutType = RTC_OUTPUT_TYPE_OPENDRAIN;
  HAL_RTC_Init(&hrtc);


  sTime.Hours = 0;
  sTime.Minutes = 0;
  sTime.Seconds = 0;
  sTime.SubSeconds = 0;
  sTime.TimeFormat = RTC_HOURFORMAT12_AM;
  sTime.DayLightSaving = RTC_DAYLIGHTSAVING_NONE;
  sTime.StoreOperation = RTC_STOREOPERATION_RESET;
  HAL_RTC_SetTime(&hrtc, &sTime, FORMAT_BIN);


  sDate.WeekDay = RTC_WEEKDAY_MONDAY;
  sDate.Month = RTC_MONTH_JANUARY;
  sDate.Date = 1;
  sDate.Year = 0;
  HAL_RTC_SetDate(&hrtc, &sDate, FORMAT_BIN);


    /**Enable the Alarm A 
    */
  sAlarm.AlarmTime.Hours = 0;
  sAlarm.AlarmTime.Minutes = 0;
  sAlarm.AlarmTime.Seconds = 0;
  sAlarm.AlarmTime.SubSeconds = 0;
  sAlarm.AlarmTime.TimeFormat = RTC_HOURFORMAT12_AM;
  sAlarm.AlarmTime.DayLightSaving = RTC_DAYLIGHTSAVING_NONE;
  sAlarm.AlarmTime.StoreOperation = RTC_STOREOPERATION_RESET;
  sAlarm.AlarmMask = RTC_ALARMMASK_MINUTES;
  sAlarm.AlarmSubSecondMask = RTC_ALARMSUBSECONDMASK_ALL;
  sAlarm.AlarmDateWeekDaySel = RTC_ALARMDATEWEEKDAYSEL_DATE;
  sAlarm.AlarmDateWeekDay = 1;
  sAlarm.Alarm = RTC_ALARM_A;
  HAL_RTC_SetAlarm_IT(&hrtc, &sAlarm, FORMAT_BIN);


    /**Enable the WakeUp 
    */
  HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 0, RTC_WAKEUPCLOCK_CK_SPRE_16BITS);


}
