Pass Bricks Form data back to page with Custom Action

How To
1

I am passing some numeric data through the Bricks form by using a custom action. This number goes to the ajax function and does some calculations. I need this updated number after calculations to be returned back to the page for displaying via JS or even PHP. So far I have not found a way to do this in the documentation. Any help would be appreciated. This is my code:

function my_form_custom_action( $form ) {  
	$fields = $form->get_fields();

	$width= $fields['idpfak'];

    $new_width = $width * 1.2;

	wp_send_json_success( $new_width );
}
add_action( 'bricks/form/custom_action', 'my_form_custom_action', 10, 1 );

This is otherwise fairly simple and straightforward via vanilla JS where the result of wp_send_json_success() is used to display on the DOM. But in Bricks, is there no possibility?

Any help would be appreciated. Thanks.
