  <p>Now, when I run app, the items are fed to <code>ListView</code> from <code>model</code> correctly, but non of the items get animated according to <code>populate</code> property. I would like all items get animated according to <code>populate</code> property. What am I missing, because in the <a href="http://doc.qt.io/qt-5/qml-qtquick-listview.html#populate-prop" rel="nofollow">populate property docs</a> states:</p>
  
  <blockquote>
    <p>populate : Transition This property holds the transition to apply to
    the items that are initially created for a view.</p>
    
    <p>It is applied to all items that are created when:</p>
    
    <p>The view is first created The view's model changes The view's model is
    reset, if the model is a QAbstractItemModel subclass</p>
