ComboBox populating inside ListView in WPF

Question

I filled ComboBoxinside ListView. Screenshot below

As shown above, it displays "M", "a", "c" instead of "Mac". Why does it divide a word into characters?

In the code behind the file, I wrote

ItemCategoryDAL itemCategoryDalObj = new ItemCategoryDAL ();
            DataTable dataTable = itemCategoryDalObj.GetAllItemCategory ();

            listView1.ItemsSource = dataTable.DefaultView;

And in the .xaml file I wrote:

<ListView Height = "148" HorizontalAlignment = "Left" Margin = "23,12,0,0" Name = "listView1" VerticalAlignment = "Top" Width = "447">
  <ListView.View>
     <GridView>
        - - - - - - - - 
        - - - - - - - -
        <GridViewColumn Header="Category Name" Width="150">
           <GridViewColumn.CellTemplate>
               <DataTemplate>
                  <ComboBox ItemsSource="{Binding Path=IC_NAME }" Width="120" />
               </DataTemplate>
           </GridViewColumn.CellTemplate>
        </GridViewColumn> 
        - - - - - - - - -
        - - - - - - - - -
     </GridView>
  </ListView.View>
</ListView>
