jquery使用tr的click()处理程序向表中添加行

我正在构建的控件包含一个可滚动的表,它有一个问题。这些行建立了一个click()函数处理程序,如下所示:

    /**
     * This function is called when the user clicks the mouse on a row in
     * our scrolling table.
     */
    $('.innerTable tr').click (function (e) {
      //
      // Only react to the click if the mouse was clicked in the DIV or
      // the TD.
      //
      if (event.target.nodeName == 'DIV'  ||
          event.target.nodeName == 'TD'     ) {
        //
        // If the user wasn't holding down the control key, then deselect
        // any previously selected columns.
        //
        if (e.ctrlKey == false) {
          $('.innerTable tr').removeClass ('selected');
        }

        //
        // Toggle the selected state of the row that was clicked.
        //
        $(this).toggleClass ('selected');
      }
    });

有一个按钮可以向表中添加如下行:

$('#innerTable > tbody:last').append('<tr>...some information...</tr>');

当成功添加行时,出于某种原因,静态行与单击处理程序一起工作,但新添加的行不工作。我有什么东西不见了吗?
