$ionicScrollDelegate problem after scrolling 1.0.0-beta.3

ionic-v1

Hello,

I tried to implement following example DOCS , for start point I used this DEMO with cats.

However if the item is more complicated, after scrolling all goes too bad.

So my item seems as:

<a class="item my-item"
        collection-repeat="item in getContacts()"
        collection-item-height="getItemHeight(item)"
        collection-item-width="getItemWidth(item)"
        ng-href="https://www.google.com/#q={{item.first_name + '+' + item.last_name}}"
        ng-style="{'line-height': getItemHeight(item) + 'px'}"
        ng-class="{'item-divider': item.isLetter}">

          <div class="row">
            <div class="col col-30">
              <img ng-if="!item.isLetter" ng-src="http://placekitten.com/60/{{55 + ($index % 10)}}">
              </div>
            <div class="col col-70">

              <div class="row">
                {{item.letter || (item.first_name+' '+item.last_name)}}
              </div>
              <div class="row">
                {{item.letter || (item.email )}}
              </div>
              </div>
          </div>        
      </a>

and this is problematic DEMO 2

Thank you,
