Unbinding models combined with the attributes plugin doesn't work

1. var Page = can.Model('Models.Page', {
2.     attributes: {
3.         Texts: 'Models.Text.models'
4.     },
5.     findOne : '/demo/canjs/page/{id}'
6. }, {});
7. var Text = can.Model('Models.Text', {
8.     findOne : '/demo/canjs/text/{id}'
9. }, {});

now I can use a page object in ejs, e.q.:

1. <%= page.attr('title') %>
2. <% page.attr('Texts').each(function( text ) { %>
3.     <%= text.attr('content') %>
4. <% }) %>

The internal counter "_bindings"  of displayed text object will set to 2.

If you remove the view, the page object will removed from internal page-store. but the text object still remains in the internal text-store with _bindings = 1.

I tryed some subtemplates to, but I got the same issue. By using many objects I will get a memory leak.

Is there some workaround, or do I understood something wrong?

Thank you for your helping.
