Hot reload not working properly?

I have this simple code here:

    // Set this character to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
    PrimaryActorTick.bCanEverTick = true;

    StaticMesh = CreateDefaultSubobject<UStaticMeshComponent>("StaticMesh");

    SpringArm = CreateDefaultSubobject<USpringArmComponent>("SpringArm");
    SpringArm->SetRelativeRotation(FRotator(-38.f, 0.f, 0.f));
    SpringArm->TargetArmLength = 500.f;
    SpringArm->bEnableCameraLag = true;
    SpringArm->CameraRotationLagSpeed = 1.f;

    Camera = CreateDefaultSubobject<UCameraComponent>("Camera");

But changing the value of the rotation of the arm spring and hitting “Compile” inside UE, shows no changes in the arm spring.
Then, if I close the editor and re-open it, then the arm-spring rotation is properly updated.

Edit: I’ve just discovered that clicking “AssetAction->Reload” from the editor, display the proper updated arm-spring rotation.
There is a way for that action to be taken automatically on Compile?
