Ion-scroll zoom and swipe


HI all, i have this:

<ion-content >
      <div id="immaginiBox" on-swipe-left="swipeLeft($index);" on-swipe-right="swipeRight($index);">
          <div class="titolo">{{item.titolo}}</div>
          <blockquote class="desc" ng-show="item.desc != null"> {{item.desc}}</blockquote>
          <ion-scroll zooming="true" direction="xy" scrollbar-x="false" scrollbar-y="false" min-zoom="1" style="width: 100%; height: 100%">
              <img class="img-responsive" ng-src="{{item.img}}" on-load="imgCaricata($event)" >


The problem is that user can not scroll up or down the page/content if he has his finger on the image. If he tries to scroll up/down via “div titolo” all works.

So, when scroll is in the min-zoom value how to permit to the user to scroll up/down ?

Swipe left/right works without problem. Only scroll up-down has problem.
