Form id attribute changing to myform--2

I have a form module with two block views. Both use the same form fields and I would like to use the same javascript. So i need all the ids to be the same no matter what.

But, Drupal is changing form element id attributes, adding two dashes and a number like 'myform--2' instead of just 'myform'. Is there a way to ensure that all forms (and elements) will have the same id attributes for any blocks I add to my module?

Below is the block info and block view code.

/**
 * Implements hook_block_info().
 */
function myform_block_info() {
  $blocks['myform'] = array(
    'info'  => t('Form side bar'),
    'cache' => DRUPAL_CACHE_GLOBAL,
  );
  $blocks['myform-fullpage'] = array(
    'info'  => t('Form full page'),
    'cache' => DRUPAL_CACHE_GLOBAL,
  );
  return $blocks;
}

/**
 * Implements hook_block_view().
 */
function myform_block_view($delta='') {
  $block = array();
  switch ($delta) {
  case 'myform':
    $block['subject'] = t('Contact Us Today');
    $block['content'] = drupal_get_form('myform');
    break;
  case 'myform-fullpage':
    $block['content'] = drupal_get_form('myform');
    break;
  }
  return $block;
}
