Dynamic roles

Hi, @ai !
Is there any way to change roles dynamically? For example, I have table cell with a form inside of it:

``` erb
<%= form_for model.name.downcase, url: adminushka_engine.items_path, method: method, class: 'form-inline', data: { role: 'cell' } do |f| %>
<%= value %>

I have triggers to switch between form and value views:

``` coffeescript
evil.block '@@item',
addHiddenFor: (items) -> items.addClass _hiddenClass
removeHiddenFrom: (items) -> items.removeClass _hiddenClass

defaults: ->
@close $ '@@items'
return

open: (cells) ->
@addHiddenFor cells.find '@value'
@removeHiddenFrom cells.find '@form'
cells.data 'role', 'activeCell'
# evil.block.vitalize cells

close: (cells) ->
@addHiddenFor cells.find '@form'
@removeHiddenFrom cells.find '@value'
cells.data 'role', 'cell'
# evil.block.vitalize cells

'click on @cell': (e) ->
@defaults()
@open e.el
return

'click on @cancel': (e) ->
@close e.el.closest '@activeCell'
return
```

After I select form view everything goes ok, but when I try to close form view via `@cancel` button nothing happens. Actually form view had been closed but it was opened again because of `click on @cancel` and `click on @cell` both were triggered by click on `@cancel` button.
I tried to resolve it via change role to `@activeCell` but it was not help.
So what do you think, may be you can suggest me another way to resolve my problem?
