From my selection on the right I dynamically construct (clone) a set of rows to the left. There I also add a REMOVE button. I can't call a jQuery function from that button. Also upon clicking the REMOVE button how can I set the checkbox of the respective row on the right to its previous state (checked). There is all the code below. Thank you.

Example </script>

<script type="text/javascript">
$(document).ready(function(){

    $("#row_remove").click(function() {       
    alert("1");
    });

 $('#tb11 tr')
 .filter(':has(:checkbox:checked)')
 .addClass('selected')
 .end()
  .click(function(event) {
    //alert("1");

    $(this).toggleClass('selected');

        if (event.target.type !== 'checkbox') {

            $(':checkbox', this).attr('checked', function() {

                if ($(this).is(":checked"))
                {
                  $(this).closest("tr").clone().appendTo("#tbl2").append("<label><input type='text' name='textfield' id='textfield'/></label><button id='row_remove'>remove</button>");

                  //ac 1
                  var findCheckBox = $("#tbl2 input:checkbox.chkclass");
                  findCheckBox.remove();

                }
                else
                {
                  var index = $(this).closest("tr").attr("id");
                  var findRow = $("#tbl2 tr[id='" + index + "']");
                  findRow.remove();
                }

            return !this.checked;

            });
        }
  });

});
</script>

Element ID attribute value must be unique!!! Remember this forever!

Check out clone() docs. This method has optional parameter "withDataAndEvents" which is false by default.
