get_categories for multi languages

I am trying to retrieve in the “content composer” the categories of projects based on the active language. But i only get the categories of the main language, never on the other languages.

My code is:

$categories = get_categories('taxonomy=jw_portfolio_categories');       

                    if(!empty($categories)){
                        foreach($categories as $cat){
                            ?><option value="<?php echo $cat->term_id; ?>"><?php echo $cat->name; ?></option><?php
                        }
                    }
    ?>
                </select>

Even if i change the backoffice active language the categories are always the same. Any ideas?

best
Pedro
