Trying to access components of a prefab

Question

I have a UI element that I want to dynamically add panels to. The panel is a prefab with two text fields inside it.

I created a class for the prefab, and the two text components are assigned to it in the inspector :

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class ListController : MonoBehaviour {
 
     public Text TextName, TextDescription;
 
 }

I then have a function which can instantiate the prefab, but im not able to access the components?

     void myFunction()
     {
         GameObject newItemInList = Instantiate( myPrefab ) as GameObject;
         ListController controller = newItemInList.GetComponent();
         controller.TextName.text = "foo";
         controller.TextDescription.text = "bar";
     }

Apparently this is not an acceptable usage of GetComponent(); ? Ive written it this way cause I saw it used like this in a tutorial, only mine is saying GetComponent in this context "cannot be inferred from the usage"

This

 ListController controller = newItemInList.GetComponent();

was incorrect. Also in the code below I added some debugging for you unstil you are satisfied with everyting

 void myFunction()
 {
     GameObject newItemInList = Instantiate( myPrefab ) as GameObject;
     ListController controller = newItemInList.GetComponent<ListController>();
     if (controller != null)
     {
         if (controller.TextName != null)
         {
             controller.TextName.text = "foo";
         }
         else
         {
             Debug.LogWarning("controller.TextName is null");
         }
         if (controller.TextDescription != null)
         {
             controller.TextDescription.text = "bar";
         }
         else
         {
             Debug.LogWarning("controller.TextDescription is null");
         }
     }
     else
     {
         Debug.LogWarning("controller is null");
     }
 }
