Universal Windows Platform - Save and retrieve text in list

I have a question for you. In XAML i created listview with name listviewtest and textbox with name txtUser. My problem is when i add this textbox txtUser to listviewtest, it will be there, but if i change text in textbox txtUser second time, listviewtest add changed textbox txtUser. What i need to do is add textbox txtUser to listviewtest and if it will be changed there will be two textboxs - first verion and changed version.
My code right now is very simple: 

List<string> namesofusers = new List<string>() { };    
string nameofuser = txtUser.Text;  
namesofusers.Add(naazov); 
listviewtest.ItemsSource = namesofusers;

This will create a new List so the old list will go away. 

List<string> namesofusers = new List<string>() { };

Declare List<string> namesofusers; elsewhere
Bind once - preferable in XAML to a public property
You many need to use an ObservableCollection rather than List

if (namesofusers == null) 
    namesofusers = new List<string>();
