Scroll top in list on input change

Hi, since beta14 my input, which scrolls a list to the top if smth is entered, is broken. The keyboard disappears after the first input (after the first letter). The keyboard should be shown until the user clicks an list item like before.

<input type="search"
  placeholder="Suche Restaurant / Ort..."
  ng-model="searchText"
  ng-focus="searchFocused = true"
  ng-blur="searchFocused = false"
  ng-change="scrollTop()">

Any suggestions for calling that scrollTop function?
