List Items disappears in MVC pattern

[babar.sajjad]

Hi

Sencha Touch 1.0.1

I had a list with names and items in it like this

Breakfast
item1
item2
Lunch
item5
.........

when the store loaded it shows me the correct list and when i moves back to page by clicking back button i see this

Breakfast
Lunch
.....
the items i am getting disappears

This happens on devices (iPad, iPhone) unable to check this on Andriod.

This is my List

Application.views.MealList = Ext.extend(Ext.List, {
    scroll: false,
    itemTpl: [
          '<tpl for=".">',
			    '<tpl if="calories != &quot;&quot; && calories != 0">',
			        '<div class="fltR"><div class="next">Calories: {calories}</div></div>',
			    '</tpl>',
			    '<div class="item">',
					'<div class="title">{title}</div>',
					'<tpl if="meal_item_count==0">',
						'<div class="name">No Items on Plate</div>',
					'</tpl>',
					'<tpl for="mealitems">',
						'<div class="name">{name}</div>',
					'</tpl>',
				'</div>',
				'<div class="clr"></div>',
        '</tpl>'
    ],
    store: 'MealStore',
    listeners:{
        itemtap: function (view, index, item, e){
			var rec = view.store.getAt(index);
            var itemsInMeal = rec.data.meal_item_count;
            var mealuuid = rec.data.uuid;
            var mealid = rec.data.id;
            var mealname = rec.data.title;
            storageObj.setItem('meal_id',mealid);
            storageObj.setItem('meal_uuid',mealuuid);
            storageObj.setItem('meal_name',mealname);
            if(itemsInMeal > 0){
            	storageObj.setItem('from_url','nutrition/meal_details');
                var url = 'nutrition/meal_details';
				Ext.redirect(url);
            }else{
            	storageObj.setItem('from_url','nutrition/plan');
                var url = 'nutrition/build';
				Ext.redirect(url);
            }
		}
    }
});
Ext.reg('mealList', Application.views.MealList);
