amfphp and flex4.5

i used drupal 6.22 and flex 4.5.
and i enabled modules
Views and AMFPHP and Services and Services Views.
I created a content type recipe and created view recipes_all in drupal.
and I enabled resource node and view and path endpoint :services/amfphp in services module .
I created a "services-config.xml" in flex 4.5
i set flex compiler : -locale en_US -services "services-config.xml"

How do I bind to data in dataGrid ?
