ScoreBoard Team kills/death

I have some trouble on detecting a players death and adding 1 to the scoreboard
This is detecting death:
public void onKill(PlayerDeathEvent e) {
String JoinedB = "Joined Blue";
String JoinedR = "Joined Red";
String Status = plugin.getConfig().getString(
"Status." + e.getEntity().getName());
if (Status.equals(JoinedB)) {
ScoreBoard.addPointB();
} else if (Status.equals(JoinedR)) {
ScoreBoard.addPointR();
}
}

Here is the ScoreBoard.addPoint:
public static void addPointR() {
int RcurrentScore = Rscore.getScore();
Rscore.setScore(RcurrentScore + 1);
updateboard();
}

public static void addPointB() {
int BcurrentScore = Bscore.getScore();
Bscore.setScore(BcurrentScore + 1);
updateboard();
}

 

Did you register your events and add @EventHandler annotations?

 

Yes I did, all my other events do work, like join and leave events
