Sencha Touch: Any event which is fired after List Items have been rendered

Simple problem but I haven't managed to find a possible solution:

I have a list in Sencha Touch with Items generated through the itemTpl property. Now I want to go through the items (after they were rendered!) in the DOM and Replace their images (using imgCache for on-device-caching of images)

The Painted event of the List doesn't help because it's fired before the Item-DOM is rendered.

EDIT: My current solution is to override the internal updateListItem method of the Ext.dataview.List, call the original updateListItem there and add there my additional functionality. Still looking for a better solution ...

The list associated store's load event is what you're looking for.

[EDIT]

As you point out in the comments the load event is not guaranteed to be thrown after the items have actually been rendered.

I think your approach is correct, but instead of adding in place your functionality, why don't you fire a custom event at the end of the overridden method, passing the list item itself, so that you can listen for that event on the list?

Something like:

updateListItem: function(item, index, info) {

    // function body ...

    me.fireEvent('listitemupdate', [item, index]);

}

That should keep your code a little more clean and reusable.
