Using HeaderDataTemplateSelector to show more then 1 column

I create a simple example using HeaderDataTemplateSelector & DataTemplateSelector.  The problem that I am having is that I can only get 1 Column Header to display.  I created both the Selector classes.  I would like to use different collections of data on the same ListView Grid.

The HeaderDataTemplateSelector is only firing 1 time.

                mHeaderTemplate2="{StaticResource mHeaderTemplate2}"                                          
                mHeaderTemplate3="{StaticResource mHeaderTemplate3}"                                          
                mHeaderTemplate4="{StaticResource mHeaderTemplate4}"/>

           
           
               
                   
               
           

           
               
           

           
               
           

           
               
           

           
                            mDataTemplate1="{StaticResource mDataTemplate1}"                                       
                mDataTemplate2="{StaticResource mDataTemplate2}"                                       
                mDataTemplate3="{StaticResource mDataTemplate3}"                                                                               
                mDataTemplate4="{StaticResource mDataTemplate4}"/>

   

   
       
           
                                    HeaderTemplateSelector="{StaticResource mHeaderTemplateSelector}"
                    CellTemplateSelector="{StaticResource mDataTemplateSelector}"/>
