drupal 7 custom content hook_theme output - drupal-modules

Question

I have a custom module created in Drupal 7 and I want it to display some HTML content. Here is how I have did.
But it is not working, what I do wrong?
<?php
/**
* Implements hook_block_info().
*/
function submenus_block_info() {
$blocks = array();
$blocks['info'] = array(
'info' => t('The submenu zone')
);
return $blocks;
}
/**
* Implements hook_block_view().
*
*/
function submenus_block_view($delta = '') {
$block = array();
$users = "edf";
$title = "sdfsd";
$block['subject'] = t('Submenu');
$block['content'] = theme('submenus_output', array('users' => $users, 'title' => $title));
return $block;
}
/**
* Implement hook_theme()
*/
function submenus_theme() {
return array(
'submenus_output' => array(
'variables' => array('users' => NULL, 'title' => NULL),
),
);
}
/**
* Display output
*/
function theme_submenus_output($somearray) {
$content = '<div>TEST</div>';
return $content;
}
?>

I checked, there is nothing wrong with that code: the new block is available in the list of blocks, and if you assign it to a region, the block is called and the code from the custom theme function is displayed.
So you could try these things:
in Administration > Configuration > Development > Performance, clear the caches
in Administration > Structure > Blocks, make sure the block is assigned to a region that exists (such as "Content") and if it is, click the "Configure" link to see if there is a filter that prevents it from being displayed.
