NavigationView and Template

[BackgroundTeam]

I have an issue with a navigationview in which there is a button with a handler, and then it's supposed to be shown a template in the detail-view of the navigationview.

Nothing happens. I have tried also to load an XTemplate outside the handler.

Thank you very much in advance.

xtype: 'navigationview',
    items: [{
        title: 'First',
        items: [{
            xtype: 'button',
            text: 'Discover!',
            handler: function(button) {
            var view = button.up('navigationview');
                        // ...
            // Here I load vars from another store in order to fill mi storemiResultado
            // This works perfectly because I have checked in the console.log
            storemiResultado.add({ID: miId, Title: miTitulo, Director: miDirector});
view.push({
    xtype: 'container',
    config: {
    store: storemiResultado,
    tpl: [
                '<div class="header">',
                    '<div>Hola</div>',
                    '<h3>{ID} {Title}</h3>',
                '</div>',
                '<p>{Director}</p>'
            ]
}
});
