Loading map by shortcode with ajax

Hi,

I’m trying to load the map as a custom shippingmethod in WooCommerce. When selecting the custom shipping method ajax loads the results.

I almost got it working. The shortcode output of the map (the div wpsl-base-gmap_0) is loaded. But the map isnt getting drawn. Its just an empty div.

Any idea how to load the map with pointers from a shortcode with ajax?
Thanks in advance.
