Why are collison events not being generated for actor component?

Hi…

Collision for actor components are not being generated in my code for some reason.

.h file
UPROPERTY(VisibleDefaultsOnly, Category = Collison)
TSubobjectPtr CollisionComp;

	void OnOverlap(AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex);

.cpp file

ATeleporter::ATeleporter(const class FPostConstructInitializeProperties& PCIP)
	: Super(PCIP)
{
	CollisionComp = PCIP.CreateDefaultSubobject<UCapsuleComponent>(this, TEXT("CapsuleComp"));
	CollisionComp->InitCapsuleSize(90, 170);
	CollisionComp->BodyInstance.SetCollisionProfileName("OverlapAll");
	CollisionComp->OnComponentBeginOverlap.AddDynamic(this, &ATeleporter::OnOverlap);		// set up a notification for when this component hits something
	//CollisionComp->OnComponentHit.AddDynamic(this, &ATeleporter::OnHit);
	RootComponent = CollisionComp;
}

void ATeleporter::OnOverlap(AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex)
{
	GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Red, TEXT("Overlap"));
}

I have attached another static mesh component to this actor through blueprints. It is a physicbody having blockallcollison. The Static mesh component is responsible for physics simulation while the capsule component detects if a character stands on it.
