WPF - how to databind multiple listbox items from the same dataset

I have 4 listbox items that are containing checkbox items. I am trying to bind them from the same Dataset but it seems I am not doing it right.

Also I would like to know if I bind checkboxes this way, how do I later access to ID values from database that are selected (since I only set Content and I didn't set selectedValuePath or something like that)?

Here is my code below:

XML

   <ListBox x:Name="grejanjeListBox" ItemsSource="{Binding}" DataContext="WinnerBazaDataSet" HorizontalAlignment="Left" Height="52" Margin="141,264,0,0" VerticalAlignment="Top" Width="307" SelectionMode="Multiple">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <CheckBox x:Name="grejanjeCheckBox"  Content="{Binding NacinGrejanja}"/>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
        <Label Content="Tip Objekta:" HorizontalAlignment="Left" Margin="30,323,0,0" VerticalAlignment="Top"/>
        <ListBox x:Name="tipObjektaListBox" ItemsSource="{Binding}" HorizontalAlignment="Left" Height="26" Margin="141,323,0,0" VerticalAlignment="Top" Width="307">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <CheckBox x:Name="tipObjektaCheckBox" Content="{Binding TipObjekta}"/>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
        <Label Content="Opis Objekta:" HorizontalAlignment="Left" Margin="31,366,0,0" VerticalAlignment="Top"/>
        <ListBox x:Name="opisObjektaListBox" ItemsSource ="{Binding}" HorizontalAlignment="Left" Height="52" Margin="142,366,0,0" VerticalAlignment="Top" Width="307">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <CheckBox x:Name="opisObjektaCheckBox" Content="{Binding OpisObjekta}"/>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
        <Label Content="Dodatno:" HorizontalAlignment="Left" Margin="31,437,0,0" VerticalAlignment="Top"/>
        <ListBox x:Name="dodatnoListBox" ItemsSource ="{Binding}" HorizontalAlignment="Left" Height="52" Margin="142,437,0,0" VerticalAlignment="Top" Width="307">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <CheckBox x:Name="dodatnoCheckBox" Content="{Binding Dodatno}" />
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

C#

private void Window_Loaded_1(object sender, RoutedEventArgs e)
    {
        WinnerBazaDataSet wds = new WinnerBazaDataSet();
        GrejanjeTableAdapter gta = new GrejanjeTableAdapter();
        TipObjektaTableAdapter tta = new TipObjektaTableAdapter();
        OpisObjektaTableAdapter ota = new OpisObjektaTableAdapter();
        DodatnoTableAdapter dta = new DodatnoTableAdapter();
        gta.Fill(wds.Grejanje);
        tta.Fill(wds.TipObjekta);
        ota.Fill(wds.OpisObjekta);
        dta.Fill(wds.Dodatno);
        this.DataContext = wds.Grejanje;
        this.DataContext = wds.TipObjekta;
        this.DataContext = wds.OpisObjekta;
        this.DataContext = wds.Dodatno;
    }
