There is a workaround to make this work with the view as you've laid it out here... But this is really not the ember way of doing it. If for some reason you need this kind of an approach, I'll append an answer for that, but I'm going to aim to fix the underlying issue.
Instead of doing this as shown here, you should instead have code that looks like the following directly in your JSP:
{{#each myObj in myCollection}}
<div>
{{#each item in myObj.items}}
<img {{action myActionHere}} src={{item.href}} alt='' class={{classNameFunction}}/>
{{/each}}
</div>
{{/each}}
If your reason for wanting to do this as a view is so that you can reuse this functionality without rewriting the code, take a look at partials which are specifically designed for that purpose.
