docs: Listen for an event on another object and triggers on itself, with the same name or a new one
  @method retrigger
  @param ev {String} event who triggers the action
  @param obj {Object} object where the event happens
  @param obj {Object} [optional] name of the retriggered event;
  @todo [xabel]: This method is repeated here and in the base view definition. There's should be a way to make it unique
