HoloLens - Smooth Rotation doesn't work

Hey, i am trying to implement a smooth rotation on a game object. The following code does a 45 degrees smooth rotation around Y Axis. But when i try to rotate one more time (after inputClicked variable changed to false) it doesn't work.. Could you help me please, i am working on this since a while and still couldn't find a solution. Thanks.

 public class RotateLeft : MonoBehaviour , IInputClickHandler {
 
     public Transform objectToRotate;    // The object which has to be rotated.
     public float smooth = 2.5f;
     public bool inputClicked;           
     public Vector3 rotationAngle;       
 
     public void OnInputClicked(InputClickedEventData eventData)
     {
         RaycastHit hit = GazeManager.Instance.HitInfo;
         if (hit.transform.gameObject.tag == "Arrows")
         {
             inputClicked = true;
         }
     }
 
 
     void Update()
     {
 
         if (inputClicked == true)
 
         {
             Quaternion target = Quaternion.Euler(rotationAngle);
             objectToRotate.transform.rotation = Quaternion.Slerp(objectToRotate.transform.rotation, target, Time.deltaTime * smooth);
             Debug.Log("ROTATE");
         }
         
         if (objectToRotate.transform.rotation.y == Quaternion.Euler(rotationAngle).y)
 
         {
             inputClicked = false;
         }
 
     }
 }
