How to change value of var of a disabled component?

I've made a pause system. I'm disabling the MouseController script when game get paused. The MouseController script is on two GOs, "GO1" and "GO2(which is parent of GO1)". The SensitivityX of GO1 is 2 and SenstivityY is 0, and of GO2 SenstivityX is 0 and SenstivityY is 2.. How can I change these value using Slider? It just shows 0. Here is the code.

 public class MenuController : MonoBehaviour
 {
 ... //Some long codes
 if(gamePaused){
 mouseControllers[1].enabled = false;
 mouseControllers[0].enabled = false;
 } else{
 mouseControllers[1].enabled = true;
 mouseControllers[0].enabled = true;
 }}

This is pauseMenu.cs which will be active during game paused:

     public class PauseCanvas : MonoBehaviour
     {
     void Start(){
     mouseControllerInScene = FindObjectsOfType<MouseController>();
      SenstivitySlider.value = ThirtySec.PlayerPrefs.GetFloat("Senstivity");
     }
     public void Change_Sensitivity_Slider(){
      Sensitivity_Text.text = Mathf.RoundToInt(SenstivitySlider.value * 100) + " %"; //Show the value changed in %
         }
     }

Since the components are disable it doesnt seem to be changing values.
