i18n_variables and complex Drupal variables

Hello,

I am developing a module and I have stuck at a point.

I have a variable, "emulov_programs_proghome" and it is something like below (Devel module Variable Editor output):

Array
(
    [value] => <p>Testing</p>
    [format] => 1
)

I want to add internalization to the "value" element of the array and I have added "emulov_programs_proghome" to settings.php $conf['i18n_variables']. Even if I change the language of the website and save the input again, the input does not change and in every language it shows the same.

How can I manage internalization in such types of variables?

Thanks.
