PlaySlotAnimationAsDynamicMontage Notify not called in C++

Hi I try to use PlaySlotAnimationAsDynamicMontage to play a sequence, I put a custom notify in the sequence. In Editor, it works. However, when U key is pressed, I play the sequence via PlaySlotAnimationAsDynamicMontage in C++. I don’t get notified. Does anyone meet this problem?
I try to use UAnimNotify_PlayMontageNotify, still not work .
