> Steps to reproduce:
> 1. open the page
> 2. you can see "subscribed" and "subscribed2" alert messages
> 3. both, Push! and Push 2! buttons reloads respective dates
> 4. click on checkbox and on the right of Push! button
> EXPECTED: only Push! should stop to work
> ACTUAL: both Push! and Push 2! stops to work
