C# Boolean Stuck as False

I have a bool in my script that is stuck as false. I tried changing if(clickCheck) to if(clickCheck == true) but it's still stuck as false. I believe this is due to the if statement being bypassed somehow. I have clickCheck set to false in the inspector so I don't know why it's being bypassed.

 using UnityEngine;
 using UnityEngine.Events;
 using UnityEngine.EventSystems;
 using UnityEngine.Serialization;
 using UnityEngine.UI;
 using System.Collections;
 public class KeyPressString : MonoBehaviour, IPointerClickHandler {
     public Text text;
     public bool clickCheck;
     public PressedStringEvent OnPress;
     void Update(){
         if(clickCheck == true){
             if(Input.inputString != null){
             OnPress.Invoke(text.text);
             clickCheck = false;
             }
         }
     }
     public void OnPointerClick(PointerEventData eventData){
         clickCheck = true;
     }
 }
 [System.Serializable]
 public class PressedStringEvent : UnityEvent<string>{}
