Uso ProMotion con la pantalla PM :: FormotionScreen.

Cómo usar la fila.on_delete devolución de llamada de Formotion en ProMotion?

Tengo este método table_data

  def table_data
    {
      sections: [{
          rows: [

          {
          title: "URL",
          key: :url,
          placeholder: "http://myapp/dj_mon/",
          action: :delete_account,
          deletable: true,
          type: :string,
          auto_correction: :no,
          auto_capitalization: :none
          }

          ]
        }]
    }
  end
