Text.text does not update

Hallo my problem is very simpel i use the event system to get a string from the player, to update the user name after that i want to clean the InputField Text Scipt but it does not update can any explain why? private Text text; private InputField inputField;

 void Start () {
     text = GetComponentInChildren<Text> ();
     inputField = GetComponent<InputField> ();
     text.text = PlayerInfo.PlayerName;
     inputField.onSubmit.AddListener ((value) => UpdatePlayerName (value));
     }
     
 private void UpdatePlayerName(string value){
     PlayerInfo.PlayerName = value;
     text.text = PlayerInfo.PlayerName;
 }

it will update in the Start function but not in the UpdatePlayerName, but the player Name is stil getting update
