Widget specific language

[olmoszamudio]

I add after this code for show in the widget the same language always, but doesn't work:

<script> zE(function() { zE.setLocale('es-419'); }); </script>

/app/code/community/Zendesk/Zendesk/data/zendesk_setup/data-upgrade-2.0.5-2.0.6.php
src/app/code/community/Zendesk/Zendesk/data/zendesk_setup/data-upgrade-1.4.2-2.0.0.php
src/app/code/community/Zendesk/Zendesk/Model/Observer.php

May be I made something wrong?
