Struts - Checkbox change not being saved to beanform

Using Struts 1.2, how can I have the a changed checkbox value carryover from the JSP to the formbean? Note that the checkbox is within a collection being iterated over using struts.

                    <logic:iterate id="bean" name="PolicyServiceTaskAssignmentForm"
                    property="tasksList" indexId="indexId"
                    type="com.llic.web.bean.PolicyServiceTaskAssignmentBean">
                    <bean:define id="idx" name="indexId" />
                    <tr>
                        <td>
                            <%
                                String idCheckedForm = "item" + idx;
                            %>
                            <html:checkbox styleId="<%=idCheckedForm%>" property="checked" name="bean" indexed="true"
                                onchange="updateCheckbox(this.id)" />
                        </td>
                        <td>
                            <bean:write name="bean" property="jobName" />
                        </td>
                        <td>
                            <bean:write name="bean" property="experienceLevel" />
                        </td>
                        <td>
                            <bean:write name="bean" property="taskName" />
                        </td>
                        <td>
                            <bean:write name="bean" property="completionTime" />
                        </td>
                    </tr>
                </logic:iterate>
