Problem of Using buttons to shift between NavigationRecognizer and ManipulationRecognizer

Apologize for if I use the thread incorrectly.

I followed Microsoft tutorial to create a project that I can modify according to my requirement. But the problem is when I press the "rotate button", I can rotate the focused object correctly, however, when I stop and release the tap gesture, the state will be changed back to 'translate' state, which means if I want to rotate again, I will need to press the rotate button once more.

I have tried so many ways to achieve this, the current most hopeful manner is :
I added two tasks in my ButtonAction script, and when I click a button, the recognizer will be changed to specific state. Here is the code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. //using UnityEngine.XR.WSA.Input;
6.  
7. namespace Academy.HoloToolkit.Unity
8. {
9.     public class ButtonAction : MonoBehaviour
10.     {
11.         public Button AssignYourButton;
12.  
13.  
14.         // Use this for initialization
15.         void Start()
16.         {
17.             //Button btn = AssignYourButton.GetComponent<Button>();
18.             AssignYourButton.GetComponent<Button>().onClick.AddListener(TaskOnClickTranslate);
19.             AssignYourButton.GetComponent<Button>().onClick.AddListener(TaskOnClickRotate);
20.             //btn.onClick.AddListener(TaskOnClickRotate);
21.             //btn.onClick.AddListener(TaskOnClickReset);
22.         }
23.  
24.         // Update is called once per frame
25.         void Update()
26.         {
27.             //Button btn = AssignYourButton.GetComponent<Button>();
28.             if (AssignYourButton.GetComponent<Button>().name == "Translate")
29.             {
30.                 TaskOnClickTranslate();
31.             }
32.             else if (AssignYourButton.GetComponent<Button>().name == "Rotate")
33.             {
34.                 TaskOnClickRotate();
35.             }
36.             //else if(btn.name == "Reset")
37.             //{
38.             //    TaskOnClickReset();
39.             //}
40.  
41.         }
42.         void TaskOnClickTranslate()
43.         {
44.             //GameObject astro=GameObject.Find
45.             Debug.Log("You have clicked the button for translation!");
46.             GestureManager.Instance.Transition(GestureManager.Instance.ManipulationRecognizer);
47.             print("Translate");
48.         }
49.         void TaskOnClickRotate()
50.         {
51.             Debug.Log("You have clicked the button for rotation!");
52.             GestureManager.Instance.Transition(GestureManager.Instance.NavigationRecognizer);
53.             print("Rotate");
54.         }
55.     }
56. }
57.  

And in the GestureManger script, there is nothing special: two recognizer initialized in Awake function, and no action in the Update function.
Here is also nothing new in GestureAction script:

Code (CSharp):

1.     private void Start()
2.     {
3.     }
4.     void Update()
5.     {
6.  
7.     }
8.  
9.     private void PerformRotation()
10.     {
11.         if (GestureManager.Instance.IsNavigating
12.             &&
13.             (!ExpandModel.Instance.IsModelExpanded ||
14.             (ExpandModel.Instance.IsModelExpanded && HandsManager.Instance.FocusedGameObject == gameObject))
15.             )
16.         {
17.             /* TODO: DEVELOPER CODING EXERCISE 2.c */
18.  
19.             // 2.c: Calculate rotationFactor based on GestureManager's NavigationPosition.X and multiply by RotationSensitivity.
20.             // This will help control the amount of rotation.
21.             rotationFactorX = GestureManager.Instance.NavigationPosition.x * RotationSensitivity;
22.             rotationFactorY = GestureManager.Instance.NavigationPosition.y * RotationSensitivity;
23.  
24.             // 2.c: transform.Rotate along the Y axis using rotationFactor.
25.             transform.Rotate(new Vector3(-1 * rotationFactorY, -1 * rotationFactorX, 0));
26.  
27.         }
28.     }
29.  
30.     void PerformManipulationStart(Vector3 position)
31.     {
32.         manipulationPreviousPosition = position;
33.     }
34.  
35.     void PerformManipulationUpdate(Vector3 position)
36.     {
37.         if (GestureManager.Instance.IsManipulating)
38.         {
39.             //GestureManager.Instance.Transition(GestureManager.Instance.ManipulationRecognizer);
40.             /* TODO: DEVELOPER CODING EXERCISE 4.a */
41.  
42.             Vector3 moveVector = Vector3.zero;
43.  
44.             // 4.a: Calculate the moveVector as position - manipulationPreviousPosition.
45.             moveVector = position - manipulationPreviousPosition;
46.  
47.             // 4.a: Update the manipulationPreviousPosition with the current position.
48.             manipulationPreviousPosition = position;
49.  
50.             // 4.a: Increment this transform's position by the moveVector.
51.             transform.position += moveVector;
52.         }
53.     }
54.

Still finding the problem of it..
