Model ViewSet Perform create method is not being called

Hi Guys,

class Customer(viewsets.ModelViewSet):
    queryset = customer.objects.all()
    serialier_class = CustomerSerializer
    permission_classes = (IsAuthenticated,)
    
    def get_queryset(self):
        return self.queryset.filter(user = self.request.user.user)
    
    def perform_create(self, serializer):
        serializer.save(user=self.request.user.user)

Here Perform Create is not working . But in same project on different app its working .
