Component Listener not working sometime

[BilkerRoger]

I use IGamePointListener To change gameobject position,
if I call create the Entity and add the PointComponent in IInitializeSystem's Initialize,It took effect immediately
But if i call the same logic in ReactiveSystem's Execute,it's not working,then I change the value on inspector,it's working,Is this normal?
I'm using extra logic to dispose,But it's so inelegant
