Hi Anton,

I am not quite sure what causes the problem in your application - I tested your scenario and everything works as expected. For your convenience here is my test jsBin example - could you please edit it and show me your current implementation? This way I would be able to check what exactly is going wrong and advice you further. Also, could you please check if there are some JavaScript errors in the browser console? Thank you in advance for your cooperation.
