TouchScreenKeyboard done

Hi.

How can I run a function once, when the mobile user is finished using the keyboard?

This is my current code:

     public string textInput = ""; //Indtast adresse
 
     private string[] geoData;
     
     private TouchScreenKeyboard keyboard;
 
     public GameObject searchText;
 
     public GameObject searchObj;
 
     void OnMouseUpAsButton() {
     
         TouchScreenKeyboard.hideInput = true;
         if(textInput == "No input") {
             textInput = "";
         }
         keyboard = TouchScreenKeyboard.Open(textInput, TouchScreenKeyboardType.ASCIICapable,false,false,false,false);
 
     }
 
 
     // Update is called once per frame
     void Update () {
     
         if(keyboard != null) {
 
             textInput = keyboard.text;
             searchText.guiText.text = textInput;
 
         }
 
         if(keyboard != null && keyboard.done == true) {
 
             print("done");
             
         }
 
     }
     
 

However, it prints done every frame after I press the 'Enter' button on my mobile keyboard. How can I make this run only once?

Best regards.
