グリッド内にボタンを表示したい

RE: グリッド内にボタンを表示したい
下記のように、プロシージャでボタンの処理を渡すようにしてやればボタンの処理は記述できそうですね。
できれば、通常のコマンドボタンのように、EventHandler の追加を行いたいです。

ただ、セル内のコマンドボタンはインスタンスとしてひとつしかないので、
どのレコードのボタンが押されたかによってイベントを切り替えるのは難しい、という認識です。

Code:
||コマンドボタンセル
{define-class public CustomCommandButtonCell {inherits StandardRecordGridCell}

  field public button:CommandButton =
      {CommandButton
        width = 40pt,
        active-traversal-container = null,
        vorigin = 0.0,
        horigin = 0.0,
        label-inset = 2px,
        test-visible? = false,
        takes-focus? = false
      }

  {method public {on-key-press ev:KeyPress}:void
    {super.on-key-press ev}
    {switch ev.value
    case KeyPressValue.enter, KeyPressValue.space do
        {self.button.take-action}
    }
  }

  field _do-action-proc:#{proc-type{r:#Record, rs:#RecordSet, cell:#RecordGridCell}:void} = null


  {constructor public {default
                          label:String = "command-button",
                          do-action-proc:#{proc-type{r:#Record, rs:#RecordSet, cell:#RecordGridCell}:void} = null
                      }
    {construct-super.StandardRecordGridCell}
    {self.button.add-event-handler
        {on Action do
            {self.do-action}
        }
    }

    set self._do-action-proc = do-action-proc
    set self.button.label = label
    set self.button.width = {make-elastic}
    {self.add-internal replace? = true, self.button}
  }

  ||ボタン押下時の処理
  {method public {do-action}:void
    def record-set =
        {if-non-null self.record, rs = self.record.record-set then
            rs
         else
            null
        }
    {self._do-action-proc self.record, record-set, self}
  }

}
||コマンドボタンカラム
{define-class public CustomCommandButtonColumn {inherits RecordGridColumn}

  {constructor public {default
                          column-resizable?:bool = false,
                          label:String = "command-button",
                          do-action-proc:#{proc-type{r:#Record, rs:#RecordSet, cell:#RecordGridCell}:void} = null,
                          ...}
    {construct-super
        column-resizable? = column-resizable?,
        {splice ...}}

    set self.cell-spec =
        {proc {col:RecordGridColumn}:RecordGridCell
            def cell = {CustomCommandButtonCell
                           label = label,
                           do-action-proc = do-action-proc
                       }
            {return cell}
        }
  }
}

||レコードの挿入と、インデックスの振りなおしを行う
{define-proc public {insert-record
                        record-set:RecordSet,
                        record:Record,
                        index:int,
                        index-field:String
                    }:void

    {with record-set.batch-events? = true do
        {for r in record-set do
            def tmp-index = r[index-field] asa int
            {if tmp-index >= index then
                set  r[index-field] = tmp-index + 1
            }
        }
        set record[index-field] = index
        {record-set.append record}
    }

}


{def rs =
    {RecordSet
        {RecordFields
            ||ボタンのカラムのフィールド
            {RecordField "RECORD-INDEX", domain = int, caption = "No."},
            {RecordField "First", domain = String, caption = "苗字"},
            {RecordField "Last", domain = String, caption = "名前"}
        }
    }
}
{def grid = {RecordGrid }}

{do
    set grid.columns  =

                        ||cell:#RecordGridCell ・・・ ボタンが格納されているセル
                        ||
                        {if-non-null r, rs then
                            {with rs.batch-events? = true do
                                ||「分割」ボタンが欧化されたら、
                                ||レコードを挿入する
                                def new-r = {rs.new-record}
                                set new-r["First"] = r["First"]

                                ||引数で指定したレコードセットに、レコードを挿入する

                                    new-r,  ||挿入するレコード

                                    ||挿入位置

                        }

            {RecordGridColumn "First"},
            {RecordGridColumn "Last"}
        }

    set grid.record-source = rs

    set grid.sort = "RECORD-INDEX"
}


||初期表示レコードの追加
{with rs.batch-events? = true do
    {for i:int = 1 to 10 do
        def new-r = {rs.new-record}
        ||レコードの並び順を保持するために、インデックスを指定します
