I'm having a little trouble understanding how the new GridField replaces some of the old interfaces. I'm trying to manage a $has_many relation on a page but when I create a new record using the GridField it doesn't automatically create the relation (just shows a drop down)

My DataObject Looks like this

class FAQ extends DataObject {

	

	static $db = array(
		'Question' => 'Varchar',
		'Answer' => 'HTMLText'
	);
	
	static $has_one = array (
		'FaqPage' => 'FaqPage'
	);
	
	static $summary_fields = array(
		'Question' => 'Question',
		'Answer' => 'Answer'
	);	

	
}

and the page looks like
class FaqPage extends Page {

	/**
	 * Static vars
	 * ----------------------------------*/
	
	static $description = 'Holds Frequently Asked Questions';



	/**
	 * Data model
	 * ----------------------------------*/

	static $has_may = array (
		'FAQs' => 'FAQ'
	);		


	/**
	 * Common methods
	 * ----------------------------------*/

	 public function getCMSFields() {
		 
		 $fields = parent::getCMSFields();
		 
		 $FAQ = FAQ::get()->filter(array('FaqPageID' => $this->ID));
		 
		 $FAQField = new GridField("FAQs", "Frequently Asked Question", $FAQ, GridFieldConfig_RelationEditor::create());
		 
		
		 
		 $fields->addFieldToTab("Root.FAQs",$FAQField);
		 
		 return $fields;
		 
	 }

	
}

Not sure what I'm missing and the documentation doesn't appear to be clear

Thanks
