Bool function not running when called from other script

Im making my first Vr game with the HTC Vive. I dont really get the whole ClickedEventArgs thing so i made my own script to check for button-pressed on the controller. but i have some problems with some of the functions. here is the relevant code:

 void Update () {
     triggerPosition = GetTriggerPos();
 }
 void LateUpdate(){
     tmptriggerpos=triggerPosition;
 }
 
 public float GetTriggerPos(){
     return controller.GetAxis(Valve.VR.EVRButtonId.k_EButton_SteamVR_Trigger).x;
 }
 public bool TriggerDown(){
     Debug.Log("TriggerDown");
     if(tmptriggerpos!=1&&triggerPosition==1){
         return true;
     }
     return false;
 }
 public bool TriggerUp(){
     Debug.Log("TriggerUp");
     if(tmptriggerpos==1&&triggerPosition!=1){
         return true;
     }
     return false;
 }
 public bool TriggerHold(){
     if(triggerPosition==1){
         return true;
     }
     return false;
 }

Now, if i run any of these functions from the Update function everything works as intended. But if i run TriggerUp or TriggerDown from another script, it doesn't even print. Im pretty positive that the function is not actually called. The TriggerHold function works perfectly when called from other scripts.

for instance, if i do this in another script it works:

 if(controller.TriggerHold()){
     Debug.Log("TriggerHeld");
 }

but if i do this:

 if(controller.TriggerDown()){
     Debug.Log("TriggerDown");
 }

it doesnt work. why???
