(new) media-upload on admin.php – UNDEFINED

Hello,

i have write last week a plugin. That plugin use the new media-upload function. That works fine.

Today i need it for an other Plugin and set up the plugin for the new media-upload.
I have enqueue the Scripts as of my last plugin.

I have following error, when i try that:
wp.media.frames/wp.media are undefined

ticket_image_window = wp.media.frames.ticket_image_window = wp.media({
	title:		"TITLE",
	button:		{
		text:	"BUTTON"
	},
	multiple:	false
});

How that works not?

wp_enqueue_script('jquery');
wp_enqueue_script('thickbox');
wp_enqueue_script('media-models');
wp_enqueue_script('media-upload');

i have add all needed scripts. it don’t work on the admin.php.
