I've got a content type and I'm trying to connect a couple of fields to related taxonomy fields

The field in content type is a term reference with autocomplete called "field_descrizione_01" (related to taxonomy term's name) with an empty field "field_udm"

The taxonomy terms has field "field_udm_ti"

I've seen a post about something similar and I've tried to modify the code, but it's not working.

* Implements hook_field_widget_form_alter().

function collegamento_field_widget_form_alter(&$element, &$form_state, $context) {

  if(isset($element['#field_name']) && $element['#field_name'] == 'field_descrizione_01') {
    $element['#ajax'] = array(
      'callback' => 'collegamento_auto_fill_callback',

function collegamento_auto_fill_callback(&$form, &$form_state) {

  $commands = array();

  if(isset($form_state['values']['field_descrizione_01'])) {
    // get selected item/node from dropdown list
    $nid = $form_state['values']['field_descrizione_01']['und'][0]['nid'];

    // load node by nid
    $node = node_load($nid);

    if($node) {

      if(isset($node->field_udm_ti['und'])) {
        // fill text field 
        $commands[] = ajax_command_invoke('#edit-field-udm', 'val', array($node->field_udm_ti['und'][0]['value']));  


  return array('#type' => 'ajax', '#commands' => $commands);

Somebody told me to modify it using load a taxonomy term using taxonomy_term_load.

So iv'e tried changing $node = node_load($nid); in $node = taxonomy_term_load($nid);

But it wasn't working

I've changed and try to use content type instead of taxonomy, but I've got other problems.
I'm using field collection module (name: man ordinaria), and now it's not working for this.
I've modified #edit-field-udm with this: #edit-field-man-ordinaria-und-0-field-udm-und-0-value
But still have nothing workig...someone can know what's the problem?
