Control lego bluetooth train with legoino library

Hi, I am controlling a lego bluetooth train. The example from the legoino-library looks like this:

/**
 * A Legoino example to control a train which has a motor connected

#include "Lpf2Hub.h"

// create a hub instance
Lpf2Hub myTrainHub;
byte port = (byte)PoweredUpHubPort::A;

void setup() {
    Serial.begin(115200);
} 


// main loop
void loop() {

  if (!myTrainHub.isConnected() && !myTrainHub.isConnecting()) 
  {
    myTrainHub.init(); // initalize the PoweredUpHub instance
    //myTrainHub.init("90:84:2b:03:19:7f"); //example of initializing an hub with a specific address
  }

  // connect flow. Search for BLE services and try to connect if the uuid of the hub is found
  if (myTrainHub.isConnecting()) {
    myTrainHub.connectHub();
    if (myTrainHub.isConnected()) {
      Serial.println("Connected to HUB");
      Serial.print("Hub address: ");
      Serial.println(myTrainHub.getHubAddress().toString().c_str());
      Serial.print("Hub name: ");
      Serial.println(myTrainHub.getHubName().c_str());
    } else {
      Serial.println("Failed to connect to HUB");
    }
  }

  // if connected, you can set the name of the hub, the led color and shut it down
  if (myTrainHub.isConnected()) {

    char hubName[] = "myTrainHub";
    myTrainHub.setHubName(hubName);
  
    myTrainHub.setLedColor(GREEN);
    delay(1000);
    myTrainHub.setLedColor(RED);
    delay(1000);
    myTrainHub.setBasicMotorSpeed(port, 35);
    delay(1000);
    myTrainHub.stopBasicMotor(port);
    delay(1000);
    myTrainHub.setBasicMotorSpeed(port, -35);
    delay(1000);
    myTrainHub.stopBasicMotor(port);
    delay(1000);

  } else {
    Serial.println("Train hub is disconnected");
  }
  
} // End of loop

I have connected a pushbutton to the board and added just alittle code. Looks like this:

    if (buttonState == HIGH){ 
      Serial.println("JA");
      myTrainHub.setBasicMotorSpeed(port, 25);
    }
    else{

    myTrainHub.setLedColor(GREEN);
    delay(1000);
    myTrainHub.setLedColor(RED);
    delay(1000);
    myTrainHub.setBasicMotorSpeed(port, 35);
    delay(1000);
    myTrainHub.stopBasicMotor(port);
    delay(1000);
    myTrainHub.setBasicMotorSpeed(port, -35);
    delay(1000);
    myTrainHub.stopBasicMotor(port);
    delay(1000);
      Serial.println("NEJ");
    }

But i get stuck here somehow, even though button is released the train keeps on going with the same speed. Text printed is "NEJ" though, so it looks correct. But isn't.

Any idea what i'm doing wrong? Thanks for suggestions.

Post all your code, not a snippet.
