editing cells in table - not working

[Olciap Berge]

Hi, I would like to have a table with editable cells, but it seems that method setItemName is never execud:

   
<s:form>
<s:iterator value="items"  status="rowstatus">
	<tr id="row_<s:property value="#rowstatus.index"/>">
		<td>
				<s:checkbox name="x" value="correct" theme="simple"/>
		</td>
		<td>
				<s:textfield name="itemName" theme ="simple"/>
		</td>

	</tr>
</s:iterator>
<s:submit value="addNew" action="Items_createNewItem" />
<s:submit value="save" action="Items_save"/>
</s:form>
 

Why is it happening and how can i solve it?
