Sencha Touch 2.2.1 not working correctly in Chrome and Android -

i have application, written in sencha touch 2.2.1, saw on current chrome (43) , on android 4.x , 5.x parts of application aren't working, while on safari on windows, mac , ios fine.

e.g. have following code on index.html getting called:

ext.viewport.items.get('main').setactiveitem(target); 

where targetis name of view loaded.

in view have following code, not called in chrome:

... listeners: {   painted: function () {     this.fireevent('ispainted');   } }, ... 

the template of view gets rendered html, listener never called.

any ideas on how can handled?
