How do I add tabledrag with ‘weight’ to admin form

I have built a fairly basic module but i’m struggling with the UX of the admin form. Essentially I need a list of items that have several values; a textfield, checkbox, select list and a button to delete them.

I’ve built all of the functionality (including the “add one more” using the example in the drupal ajax examples module) and its working great, except now I need to be able to reorder the items and the webmin style up/down buttons are not good UX. I’ve been hacking to no avail at numerous examples like: http://www.urbaninsight.com/2012/09/11/creating-table-with-draggable-weights-in-drupal-7

It doesn’t appear that theme_hook_form is being called so I can’t inject the weight javascript, styles or markup.

I added this to the .module file:

function module_cache_theme() {   dpm("themehook");   return array(     'theme_module_settings_form' => array(       'file' => 'module_form.inc',       'arguments' => array('form' => NULL),     ),   ); } 

The menu item is in the hook_menu:

  $items['admin/config/development/module'] = array(     'title' => 'module',     'description' =>'',     'page callback' => 'drupal_get_form',     'page arguments' => array('module_settings_form'),     'access arguments' => array('administer site configuration'),     'file' => 'module_form.inc',   ); 

When the cache is regenerated I get a dpm message but the method theme_module_settings_form is never being triggered.

Ideas?
