datetimepicker within display tag

[Grace Phone]

I want to show datetimepicker for every row of display tag table.
I use the following code.

<display:table class="displayTable" id="myList"
        name="mytList" requestURI="viewList.action?" pagesize="15">
...
        <display:column class="colStartDate">
            <sx:datetimepicker id="taskEndDate" name="startdate" displayFormat="dd-MMM-yyyy"/>
        </display:column>
...
</display:table>

But for now, I can only see it at the very first row.
How can I modify to display datetimepicker for every row of display tag table?
