WordPress Media Upload Plugin 3.5 JS PHP

I have a small issue creating a small plugin. I am trying to achieve a gallery meta box using Media Upload 3.5.

At this point I am able to upload images, but when trying to update the image. I wont get the same Post->ID as the Attachments (I strongly believe this is where the issue is at.) Perhaps I am doing something wrong with the shortcode api snippet or the way I’m passing my data.

Above is the code for the js and some functions. If it helps I used “shibashake” WordPress Media Manager as a Starting Point.

function media_view_settings( $settings, $post ) {

    $shortcode = '[gallery ';
    $ids = get_post_meta( $post->ID, 'gallery_ids', TRUE );
    $ids = array(0);
    if ( is_array( $ids ) ) {

        $shortcode .= 'ids="' . implode( ',', $ids ) . '"]';

    } else {

        $shortcode .= 'id="' . $post->ID . '"]';

    }

    $settings['Gallery'] = array('shortcode' => $shortcode);
    return $settings;
}

function metabox( $post ) {
    global $post;

    wp_nonce_field( 'gallery', 'gallery_nonce');

    $gallery = get_post_meta( $post->ID);

    echo '<div id="gallery-container">';
        echo '<p>' . do_shortcode( '[gallery ids="' . $gallery[ 'gallery_ids' ][0] . '" link="none"]' ) . '</p>';
        echo '<p><a href="#" id="open-media" class="button button-primary" title="' . esc_attr__( 'Add Media', 'gallery-meta-box' ) . '">' . __( 'Add Media', 'gallery-meta-box' ) . '</a></p>';
        echo '<p><input type="hidden" id="gallery_ids" value="' . $gallery[ 'gallery_ids' ]. '" /></p>';
    echo '</div>';

}

    public function save_content( $post_id ) {

    // Checks save status
    $is_autosave = wp_is_post_autosave( $post_id );
    $is_revision = wp_is_post_revision( $post_id );
    $is_valid_nonce = ( isset( $_POST[ 'gallery_nonce' ] ) && wp_verify_nonce( $_POST[ 'gallery_nonce' ], 'gallery' ) ) ? 'true' : 'false';

    // Exits script depending on save status
    if ( $is_autosave || $is_revision || !$is_valid_nonce ) {
        return;
    }

    // Checks for input and sanitizes/saves if needed
    if( isset( $_POST[ 'gallery_ids' ] ) ) {
        update_post_meta( $post_id, 'gallery_ids', sanitize_text_field( $_POST[ 'gallery_ids' ] ) );
    }
}

JS

jQuery(document).ready(function(){ wp.media.GalleryMetabox = {

    frame: function() {
        if ( this._frame )
            return this._frame;

        var selection = this.select();
        this._frame = wp.media({
            id:         'my-frame',

            state:      'gallery-edit',
            title:      wp.media.view.l10n.editGalleryTitle,

        this._frame.on( 'update', function() {

            var library = controller.get('library');
            // Need to get all the attachment ids for gallery
            var ids = library.pluck('id');

            // AJAX send (isn't currently working)

            }).done( function() {
                window.location = wp.media.GalleryMetabox.link;
            });

            /*

            controller.off('reset');
            */

            // Send the attachment URL to our custom input field via jQuery.
            jQuery('#gallery_ids').val( ids );

        });
        return this._frame;
    },

    // Gets initial gallery-edit images. Function modified from wp.media.gallery.edit:513

            attachments, selection, state;

        // Bail if we didn't match the shortcode.
        if ( ! shortcode )
            return;

        // Ignore the rest of the match object.
        shortcode = shortcode.shortcode;

        if ( _.isUndefined( shortcode.get('id') ) && ! _.isUndefined( defaultPostId ) ) {
            shortcode.set( 'id', defaultPostId );
        }

        attachments = wp.media.gallery.attachments( shortcode );

            props:    attachments.props.toJSON(),
            multiple: true
        });

        selection.gallery = attachments.gallery;

        // Fetch the query's attachments, and then break ties from the
        // query to allow for sorting.
        selection.more().done( function() {
            // Break ties with the query.
            selection.props.set({ query: false });
            selection.unmirror();
            selection.props.unset('orderby');
        });

        return selection;
    },

    init: function() {
        jQuery('#open-media').click( function( event ) {
            event.preventDefault();
