How to call a method of my Custom Editor when I reset the target MonoBehavior ?

Hi everybody !!

I think it's my first thread on the forum ! I will be glad to read your answers.

Here's my problem :
I have a Custom Editor for a specific MonoBehavior.
In my MonoBehavior script I have a simple method Reset() when player right-click -> Reset in the Inspector.
It works perfectually, but I have a more complexe Custom Inspector, and I need to call a method to reset it. I can't find any way to do it... Do you have any idea ?

Code (CSharp):

1. /* Inherited MonoBehavior class */
2. public void Reset()
3. {
4.       Anchors = new List<Anchor>();
5.       Controls = new List<Vector3>();
6.       AddAnchor();
7.       AddAnchor();
8.       //Maybe I can reset the custom inspector here ?
9.  
10.  }

Or maybe I can watch for the monobehavior's reset directly inside my inspector ? But how ?

Thank you !!
