In Custom Tag how to add h:commandbutton with action

Question

Hi, I created a custom tag in facelets (& Seam), below is the code snippet
<tag>
<tag-name>customdiv</tag-name>
<component>
<component-type>customtag.MyCustomTag</component-type>
<component-class>com.mydomain.testing.customtag.MyCustomTag</component-class>
</component>
</tag>
In this class I am using ResponseWriter to generate the content.
I am trying to add a button and associate action to it but it doesn't provide me any option to associate action to the commandbutton
"<h:commandButton action="#{childdiv.addChildDiv}" value="add div"></h:commandButton>"
Also the XHTML doesn't even recognize the h:commandbutton tag
"HtmlCommandButton htmlCommandButton = new HtmlCommandButton();
writer.startElement("h:commandButton", htmlCommandButton);
writer.writeAttribute("value", "add div", "");
writer.endElement("h:commandButton");"
Please suggest

</h:form>MyBean (session scoped)private List<DataItem> dataList; // +getter
private List<SelectItem> selectItems; // +getter

    selectItems = new ArrayList<SelectItem>();
    selectItems.add(new SelectItem("value1", "label1"));
    selectItems.add(new SelectItem("value2", "label2"));
    selectItems.add(new SelectItem("value3", "label3"));
public void add() {
    dataList.add(new DataItem());
public void save() {
    // Do your thing to save the dataList. All values are already set in there.
    // Just doing a sysout here to prove it.
    System.out.println("Saved: " + dataList);
}DataItemprivate List<String> selectedItems; // +getter +setter
// Just for convenience so that it is readable in the sysout.
public String toString() {
    return "DataItem[" + selectedItems + "]";
