advice on using subcomponent in ember table

I have an ember-table with editable cells, via overriding TableCell. I would like to use ic-autocomplete in the edit widget. Is there any way to specify that the ic-autocomplete actions be targeted at the tablecell-derivative (view), rather than having them hit the ember-table component, which is the "controller" in this context?

Alternately, I thought of using a "render" tag and creating a controller specific to the table row. But then it would seem that the edit widget would be just the render tag and the I would have to create yet another template w/ the ic-complete layout. Is this really the case, or can I somehow simplify?
