setActiveItems issues

[slmd]

Hi all,

I am having hard times understanding why i can't get back to the previous panel using this code below

appsDetails = Ext.extend(Ext.Panel, {
    layout: 'fit',
    scroll: 'verticall',
    
    initComponent: function() {
        
        this.dockedItems = [{
            xtype: 'toolbar',
            items: [{
                ui: 'back',
                scope: 'this',
                handler: function() {
                    
                    console.log(this.ownerCt) //This returns "undefined"
                    
                    this.ownerCt.setActiveItem(this.prevCard, {
                        type: 'slide',
                        reverse: true,
                        scope: this,
                        after: function() {
                            this.destroy();
                        }
                    })
                }
            }]
        }];
        
        this.items = [{
            styleHtmlContent: true,
            tpl: description,
            data: this.record.data
        }];
        
        appsDetails.superclass.initComponent.call(this);
    }
});

Actually when i click on the back button i have this error :
Uncaught TypeError: Cannot call method 'setActiveItem' of undefined

Thanks for your help

Sorry for having bothered you with this. I had to change this line "scope: 'this'," to this "scope: this,"
