Dynamic roles

[vforvova]

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

<%= form_for model.name.downcase, url: adminushka_engine.items_path, method: method, class: 'form-inline', data: { role: 'cell' } do |f| %>
  <span data-role='value'><%= value %></span>
  <div class="input-group hidden" data-role="form">
    <%= f.text_field attribute, value: value, class: 'form-control' %>
    <span class="input-group-btn">
      <button class="btn btn-success" type="submit" data-role="update">
        <span class="glyphicon glyphicon-ok"></span>
      </button>
      <button class="btn btn-danger" type="button" data-role="cancel">
        <span class="glyphicon glyphicon-remove"></span>
      </button>
    </span>
  </div>
<% end %>

I have triggers to switch between form and value views:

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?

You can add custom filter, which will add @rebindRoles method to every block.

Or you can send PR with evil.block.rebindRoles(@) method.

Ok, I'll have a look
