Webform - trying to set submit handler On a Drupal 7 Webform I've added a button using a markup field like this:

&lt;button name="get" value="" type="submit" class="primary-submit submit" id="get"&gt;
Get Address
&lt;/button&gt;


I am directing it to a submit handler like this:

function new_webform_form_alter(&amp;$form, &amp;$form_state, $form_id) {
  if ($form_id == 'webform_client_form_88') {
    $form['submitted']['name']['get']['#submit'][]='new_webform_get_submit';
    dpm($form);
  }
}


I can tell the button #submit is being changed, but the whole form is submitted instead of executing the handler code. What am I doing wrong?
Turns out the form was not actually being submitted but the custom handler was not being processed because the form validation was failing. I disabled it with

$form['submitted']['name']['get']['#limit_validation_errors']=array();


and now the handler works.
