C# GameObject disabled scripts of its children after SetActive(false)

Here's the situation:

A have a bunch of buttons and an Input Text Field as children to a Panel. I need to set them invisible at the start of the scene and visible after some conditions are met. For that i use this:

 public void HidePanel()
     {
         Panel.gameObject.SetActive(false);
     }
 
 .....
 .....
 .....
 .....
 
 public void ShowPanel()
     {
         Panel.gameObject.SetActive(true);
     }

After I set the Panel active, it sure does pop-up in the scene and the buttons attached to it too. However the buttons animation are dead and so is the InputTextField I have in there too. I can't even type in the Input Text Field. I use the regular buttons and Input Text Field that come with Unity.

I tried putting the panel in a different Canvas, same thing happened. I tried putting the panel in a differente Scene, same result.

Please help, I have been in this situation for the past 4 days and I can't be stuck in this situation for much more time, for I need to delivery this project soon.

My english is not the best, so I'm sorry if it is a confusing question. If you need more information, please ask.
