Input system .canceled is not working

I’ve been trying to get my performJump method to detect when the jump button is released, but the code I put in isn’t working for some reason and it also won’t let me jump now. I previously asked about how to get the program to detect it, but it didn’t end up working, and looking at an old project it was working perfectly fine. I don’t know what I did wrong here, someone please help.

private void performJump(InputAction.CallbackContext ctx)
    {
        
        if (ctx.performed && isGrounded)
        {
            player.velocity = new Vector2 (player.velocity.x, jumpSpeed * Time.deltaTime);
            Debug.Log ("boing");
        }
        if (ctx.canceled && !isGrounded)
        {
            player.velocity = new Vector2 (player.velocity.x, 0);
        }
        

    }

private void OnEnable()
    {
        playerControls.Enable();
        jump.action.started += performJump;
        jump.action.canceled -= performJump;
    }

    private void OnDisable()
    {
        playerControls.Disable();
    }
