Listview with ComboBox

Question

Hi,

I am using a listview which has the combobox.
I bind the listview properly but i am not able to bind the combobox of listview from my code behind file.

Code Snippet

This what i am doing in my XAML File

<DataTemplate x:Key="template">

   <ComboBox Name="cmbAgent"  DisplayMemberPath="Agents"  ItemsSource="{Binding}"        IsSynchronizedWithCurrentItem="False"  HorizontalAlignment="Center" Width="80">      </ComboBox>

 </DataTemplate>

<ListView Name="ListView1" ItemsSource="{Binding}">
            <ListView.View>               
                <GridView>

               <GridViewColumn DisplayMemberBinding="{Binding Path=SetupStepName}"     Header="Description" Width="200"/>

                    <GridViewColumn Header ="Agent" CellTemplate="{StaticResource template}" Width="100"/>                 
                </GridView>
            </ListView.View>
        </ListView>

Code Snippet

This my .cs File
I load the dataset
dsFormLoad = ObjParameterData.GetIssuerAgent(1149);
I bind the dataset to the dataview which will bind to the listview

dvFormLoad = dsFormLoad.Tables[0].DefaultView;
my another table in dataset which will bind to another dataview name dvAgent

dvAgent = dsFormLoad.Tables[1].DefaultView;
Now i bind the first dataview to the Listview like

 ListView1.DataContext = dvFormLoad;

Now I want to bind the another dataview to the combobox which is inside the listview.
How can i achieve this.
i am not getting the name of  combobox to bind.
