Autocomplete cached form after search page

My form has autocomplete (page) field with multiselect.
Default selected 2 items

In form: Field name __________ 2>

Then I select five other items

  • By js [2] change to [5]

But after click BACK button, form has only 2 items: Field name __________ 2> (5 return to 2)
And input field not has new items id… Cached? Why?
All my code from last autocomplete example, I am using latest Framework7

P.S. If I use popup - all OK…

Sorry for my English…

Do you have live example or JSFiddle?
