With MVVM your code behind will look as bellow:
There is no change in XAML.

public partial class MainWindow : Window
{
ViewModel objViewModel = null;
public MainWindow()
{
InitializeComponent();
objViewModel = new ViewModel();
this.DataContext = objViewModel;
//bind item source of list to ObservableCollection
lst.ItemsSource = objViewModel.Specs;
}
//on click of add + button
private void ADD_Click(object sender, RoutedEventArgs e)
{
objViewModel.Specs.Add(txtSpec.Text);
}
}
public class ViewModel
{
public System.Collections.ObjectModel.ObservableCollection Specs
= new System.Collections.ObjectModel.ObservableCollection();
public ViewModel()
{
}
}

Try bellow code:
//Code behind

namespace WpfApplication1
{
///
/// Interaction logic for MainWindow.xaml
///
public partial class MainWindow : Window
{
System.Collections.ObjectModel.ObservableCollection Specs
= new System.Collections.ObjectModel.ObservableCollection();
public MainWindow()
{
InitializeComponent();
//bind item source of list to ObservableCollection
lst.ItemsSource = Specs;
}
//on click of add + button
private void ADD_Click(object sender, RoutedEventArgs e)
{
Specs.Add(txtSpec.Text);
}
}
}

//XAML:
