Input not reqistered new input system

So when i try to rotate using my scroll wheel i usally dont get any input at all, it works some times but most of the time it returns 0 as the input. I am using unitys new input system.

using System.Collections;
using System.Collections.Generic;
using System.Threading;
using UnityEngine;
using UnityEngine.InputSystem;

public class CameraController : MonoBehaviour
{
    public InputActionAsset cameraControls;
    private InputActionMap cameraMap;
    private InputAction panAction;
    private InputAction rotateAction;
    private InputAction mouseRotateAction;

    public float panSpeed = 10f;
    public float rotationSpeed = 10f;

    private Vector3 forwardDirection;

    float rotateAmount;

    private void Start()
    {
        forwardDirection = transform.forward;
    }

    private void Update()
    {
        Pan();
        Rotate();
    }

    private void Pan()
    {
        Vector2 panInput = panAction.ReadValue<Vector2>();

        float panX = panInput.x;
        float panY = panInput.y;

        Vector3 panMovement = forwardDirection * panY + transform.right * panX;

        transform.position += panMovement * panSpeed * Time.deltaTime;
    }

    private void Rotate()
    {
        float rotateInput = rotateAction.ReadValue<float>();

        transform.Rotate(Vector3.up * rotateInput * rotationSpeed * Time.deltaTime);

        forwardDirection = transform.forward;
    }

    private void MouseRotation(InputAction.CallbackContext context)
    {
        Vector2 mouseDelta = Mouse.current.delta.ReadValue();

        rotateAmount = mouseDelta.x * rotationSpeed * Time.deltaTime;

        transform.Rotate(Vector3.up, rotateAmount);
    }

    private void MouseRotationOff(InputAction.CallbackContext context)
    {
        Debug.Log(rotateAmount);
    }

    private void OnEnable()
    {
        cameraMap = cameraControls.FindActionMap("CameraMap");
        panAction = cameraMap.FindAction("PanAction");
        rotateAction = cameraMap.FindAction("RotateAction");
        mouseRotateAction = cameraMap.FindAction("MouseRotateAction");

        mouseRotateAction.started += MouseRotation;
        mouseRotateAction.canceled += MouseRotationOff;

        cameraMap.Enable();
    }

    private void OnDestroy()
    {
        cameraMap.Disable();
    }
}

So solved it by remaking the code a bit here is the finished product!

using System.Collections;
using System.Collections.Generic;
using System.Threading;
using UnityEngine;
using UnityEngine.InputSystem;

public class CameraController : MonoBehaviour
{
    public InputActionAsset cameraControls;
    private InputActionMap cameraMap;
    private InputAction panAction;
    private InputAction rotateAction;
    private InputAction mRotateAction;

    public float panSpeed = 10f;
    public float rotationSpeed = 10f;
    public float mouseRotationSpeed = 10f;

    private Vector3 forwardDirection;
    private void Start()
    {
        forwardDirection = transform.forward;
    }

    private void Update()
    {
        Pan();
        Rotate();
    }

    private void Pan()
    {
        Vector2 panInput = panAction.ReadValue<Vector2>();

        float panX = panInput.x;
        float panY = panInput.y;

        Vector3 panMovement = forwardDirection * panY + transform.right * panX;

        transform.position += panMovement * panSpeed * Time.deltaTime;
    }

    private void Rotate()
    {
        float rotateInput = rotateAction.ReadValue<float>();

        transform.Rotate(Vector3.up * rotateInput * rotationSpeed * Time.deltaTime);

        forwardDirection = transform.forward;
    }

    private void MouseRotation(InputAction.CallbackContext context)
    {
        if (!Mouse.current.middleButton.isPressed)
            return;

        float mouseRotate = context.ReadValue<Vector2>().x;

        transform.Rotate(Vector3.up * mouseRotate * mouseRotationSpeed * Time.deltaTime);

    }

    private void OnEnable()
    {
        cameraMap = cameraControls.FindActionMap("CameraMap");
        panAction = cameraMap.FindAction("PanAction");
        rotateAction = cameraMap.FindAction("RotateAction");
        mRotateAction = cameraMap.FindAction("MRotateAction");

        mRotateAction.performed += MouseRotation;

        cameraMap.Enable();
    }

    private void OnDisable()
    {
        mRotateAction.performed -= MouseRotation;

        cameraMap.Disable();
    }
}
