How to dynamic construct checkbox and get the selected status

Question

Hello. I'm new to the JSF development. I need to dynamically generate the table data based on the selection of database table name . The first column is the checkbox which will allow user to select one or more rows for modification, deletion, etc. Here is the partial code that i wrote to add checkbox to the first column of the table in the backing bean. I would like to generate the same checkbox binding as we did from Design Palette.
<webuijsf:checkbox binding="#{UpdateTable.checkbox}" id="checkbox" selected="#{UpdateTable.selectedRow}"/>
Checkbox checkbox = new Checkbox();
checkbox.setValueBinding("name", getApplication().createValueBinding("#{currentRow.value['ROWID_VALUE']}"));
checkbox.setValueBinding("selected", getApplication().createValueBinding("#{UpdateTable.selectedRow}"));
tableColumn1.getChildren().add(checkbox);
Once user checked the box, the backing bean should be able to catch the event.
* Records whether or not the current row should be marked as selected,
* based on the state of the checkbox.
public void setSelectedRow(boolean b) {
System.out.print("click");
TableRowDataProvider rowdp = (TableRowDataProvider) getBean("currentRow");
RowKey rowKey = rowdp.getTableRow();
if (checkbox.isChecked()) {
selectedRows.add(rowKey);
} else {
selectedRows.remove(rowKey);
But it's not working as I thought. I'm not sure if I can binding selected with backing bean attribute like I did above. Please help!!!
