Auto Close modal on form submition

Hi,

Thank you for this easy to use module. I'd like to a for a way to auto close the modal on user submition if the form doesn't have errors. Can you please provide some advise?

I have search in the web and I get to the ctools_modal_command_dismiss() function but I'm not sure where to put it. with this module i think create the node with entity_create but later how to autoclose the modal.

Thank you
