XAML nested DataTemplate data-binding

I have an ItemsControl which has its ItemsSource set with a Binding to an ObservableCollection on my ViewModel. I am using a Button control within its ItemTemplate to display my data and I am using a DataTemplate within the Button and none of the Binding data is being displayed. Below is the XAML in question:

<ItemsControl ItemsSource="{Binding Path=ConnectedInstruments}" HorizontalAlignment="Left">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal" />
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Button Height="60" VerticalAlignment="Top">
                <Button.ContentTemplate>
                    <DataTemplate>
                        <StackPanel>
                            <TextBlock Text="{Binding Path=ModelCode}" />
                            <TextBlock Text="{Binding Path=SerialNumber}" />
                        </StackPanel>
                    </DataTemplate>
                </Button.ContentTemplate>
            </Button>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

Neither TextBlock controls within the Button DataTemplate are being populated. I understand this has something to do with the Binding path, however I am at a loss as to what I am doing wrong. Can someone put me on the right track please?

EDIT

public class Instrument
{
    public string ModelCode { get; set; }
    public string SerialNumber { get; set; }
}

public class ViewModel
{
    public ObservableCollection<Instrument> ConnectedInstruments { get; set; }
}

I know that the ItemsControl is Binding correctly with the ObservableCollection as the correct count of Button controls are being displayed, only the templated data is missing.

Any specific reason you need to use ContentTemplate instead of directly setting Button's Content like this? :

<ItemsControl.ItemTemplate>
    <DataTemplate>
        <Button Height="60" VerticalAlignment="Top">
            <StackPanel>
                <TextBlock Text="{Binding Path=ModelCode}" />
                <TextBlock Text="{Binding Path=SerialNumber}" />
            </StackPanel>
        </Button>
    </DataTemplate>
</ItemsControl.ItemTemplate>
