Get posts after a specific date

This is exactly what I’m looking to do using Version 2.0-beta15 with a custom post type that inherits from the WP_REST_Posts_Controller, but sorts based on an acf field. Unfortunately this isn’t working for me. 🙁

I’m hitting the following endpoint:
/wp-json/wp/v2/almanac_entry?per_page=3&filter[orderby]=acf_almanac_date&after=2016-12-23T00:00:00&filter[date_query[column]]=acf_almanac_date

and it’s returning three results (should be two) where two are after the date listed, and the third is before the date listed.

Here’s how I’m registering my actions:

add_action( 'init', 'register_custom_post_types', 25 );
function register_custom_post_types() {
	global $wp_post_types;

	$post_type_name = 'almanac_entry';
	if( isset( $wp_post_types[ $post_type_name ] ) ) {
		$wp_post_types[$post_type_name]->show_in_rest = true;
		$wp_post_types[$post_type_name]->rest_base = $post_type_name;
		$wp_post_types[$post_type_name]->rest_controller_class = 'WP_REST_Posts_Controller';
	}
}

add_action( 'rest_api_init', 'wp_rest_add_custom_fields' );
function wp_rest_add_custom_fields() {
	register_rest_field('almanac_entry', 'acf_almanac_date', array (
    'get_callback' => function($object, $field_name, $request) {
      return get_post_meta( $object[ 'id' ], 'almanac_date', true );
    },
    'update_callback' => null,
    'schema'          => null,
  ));
}

I’m new to doing WP dev, so I may have done this wrong. I’m wondering if maybe it’s due to the priority not being set in add_action?

Any help is much appreciated.
