Multilingual settings form using i18n variable

Question

I'm using a settings form for my module and I'm trying to make some of the fields multilingual.

I've declared the multilingual variables with hook_variable_variable_info (and with hook_variable_group_info for my custom group):

function MYMODULE_variable_info() {
  $variable['my_variable_name'] = array(
    'type' => 'string',
    'title' => t('My title'),
    'default' => MY_DEFAULT_VALUE,
    'description' => t('My description.'),
    'localize' => TRUE,
    'group' => 'my_group'
  );

  return $variable;
}

I've added my settings form (one field for example)

function MYMODULE_settings_form() {
  $form = array();

  $form['my_variable_name'] = array(
    '#type' => 'textfield',
    '#title' => t('My title'),
    '#title_display' => 'before',
    '#default_value' => variable_get_value('my_variable_name'),
  );

  return system_settings_form($form); 
}

And as you can see I've used system_settings_form($form) to save my form fields as variables.
I've checked my new variable at 'admin/config/regional/i18n/variable' and the form shows that it's a multilingual form and multilingual field, but when I'm switching to another language the value isn't saved. (Only the English version saves and changes the value for all languages)

Thanks.

Not sure if it's the best solution at all, but one way would be getting the langcode from the url parameters:

$langcode = !empty($_GET['variable_realm_key_language']) ? $_GET['variable_realm_key_language'] : $GLOBALS['language']->language;

And then you can use i18n_variable_get() using the $langcode as the second parameter.

I was in a need to create translatable strings for text entered using Page title module and I used the following code to create variable

function module_variable_info($options) {
    $variables['page_title_type_news_and_event'] = array(
    'type' => 'text',
    'title' => t('Page title CT New Events', array(), $options),
    'default' => '',
    'description' => t('Module : Page title', array(), $options),
  );

  return $variables;
}

Now I can see them in others tab at admin/config/regional/i18n/variable and I enabled the check box there

Then I can translate my string at admin/config/system/variable and at others tab
