BeginCursorOver is not being triggered when added from C++

Hi everyone!
I have WCharacter derived from ACharacter and in constructor I subscribe for BeginCursorOver event using such syntax:

AWCharacter::AWCharacter()
    :Super()
{
    PrimaryActorTick.bCanEverTick = true;

    OnBeginCursorOver.AddDynamic(this, &AWCharacter::CursorOver);
    OnEndCursorOver.AddDynamic(this, &AWCharacter::CursorOut);
}

...

void AWCharacter::CursorOver()
{
    if(GEngine)
    {
        GEngine->AddOnScreenDebugMessage(1, 5.f, FColor::Green, TEXT("Cursor Over"));
    }
}

void AWCharacter::CursorOut()
{
    if (GEngine)
    {
        GEngine->AddOnScreenDebugMessage(1, 5.f, FColor::Green, TEXT("Cursor Out"));
    }
}

Then i derive few Blueprints with meshes and capsules from WCharacter and place them on the stage - nothing is happen when I hover them with mouse during the game. From the other side - if i implement ActorBeginCursorOver through the blueprints visual scripting for each character like that

everything works just fine. I suppose i missed something in code.

P.S. player controller has mouse over events enabled

If I remember correctly I had an issue like this too. I fixed it by playing with the collisions. Try out different collision presets.

nope. I moved event subscription to BeginPlay method and everything works now. I still wonder why it is not working from constructor though.
