Loosing focus on input field when keyboard appears

On this project I still use beta 1.0.0-beta.14

When I tap input field, I can see a focus cursor flashing on it , but then keyboard slides in, and I lose focus on input, and if I start typing, I don’t see any text changing and classes on input are ng-unclicked and it has readonly attribute, but then if I click on input again, I can see my text that I was typing, and all classes are changing to correct ones.
