Same Video is playing in Nested List leaf ?

Hi All

The same video is showing up in all of the leafs in my nestedList .

When I do check it , I do see the correct video listed as the source.

But whatever video I start with that is the video that would play on all the leafs in the nested list.

Is their something I am missing?

Thanks

Jim

HTML Code:

    Ext.define('TuT.view.NestedList',{   extend:'Ext.NestedList',
   xtype:'nestedList',
   
   requires:['Ext.Video'],
   
   config:{
       title:'NestedList',
       iconCls:'star',
       fullscreen: true,
       scrollable:true,
       styleHtmlContent:true,
       styleHtmlCls:'homepage',
       displayField: 'text',
       store: 'TreeStore',

   detailCard:{
       xtype:'video',
    
     },
         
    }
});

HTML Code:

    Ext.define('TuT.model.ListItem', {
    extend: 'Ext.data.Model',
   config:{
        fields:['text','url']
       }
})

HTML Code:

    Ext.define('TuT.store.TreeStore', {
extend: 'Ext.data.TreeStore',
config: {
model: 'TuT.model.ListItem',
defaultRootProperty:'items',
root: {
items: [
{
text: 'Drinks',
items: [
{
text: 'Water',
items: [
{ text: 'Still', url: ['http://ift.tt/1zhwPM8' ], leaf: true },
{ text: 'Sparkling', url: ['http://ift.tt/1zhwNUy' ], leaf: true },
{ text: 'JB', leaf:true}

},
{ text: 'Soda', leaf: true }

{ text: 'Pretzels', leaf: true },
{ text: 'Wasabi Peas', url: ['http://ift.tt/1wGQMZg '], leaf: true}
]
}
]
}
}
});

HTML Code:

    Ext.define('TuT.controller.NestedList', {
    extend: 'Ext.app.Controller',
    
  config: {
  refs: {
  nestedList: 'nestedList'
        },
        control: {
                'nestedList':{
            
                 leafitemtap: function(nestedList, list, index, target, record) {
                    var detailCard = nestedList.getDetailCard();


                     detailCard.setUrl(record.get('url'));
                },
            }

    });
