Here maps change language for map controls dynamically

With here maps there is possibility to change language for both layers and controls. Here is example from here maps. http://jsfiddle.net/gh/get/jquery/2.1.0/heremaps/jsfiddle-github/tree/master/map-multi-language-support . The problem I'm having with this example is that it changes control translation with this line of code:

var ui = H.ui.UI.createDefault(map, defaultLayers, 'zh-CN');.

It's good for initial language, but what if I have a button that would change language, would I need to recreate this ui variable every time I would want to change control language? Is there no method like H.ui.UI.setLocale or something(I tried to search but couldn't find).
