Passing attribute that can be "target" in JSF Composite Component - jsf-2

Question

I created some composite components and need to pass attribute that could be used as "target" in Primefaces p:dataExporter and "datasource" in p:columnToggler.
First attr. "FormID" works as expected, but second one "tableID" do not. It is used under contextMenu. Code:
<composite:interface>
<composite:attribute name="FormID"/>
<composite:attribute name="tableID"/>
</composite:interface>
<composite:implementation>
<p:contextMenu for="#{cc.attrs.FormID}">
<p:submenu label="Export">
<p:menuitem value="Export to XLS" onclick="$('#exportToXLS').click()" />
</p:submenu>
<p:menuitem value="Columns" onclick="$('#toggler').click()" />
</p:contextMenu>
<p:commandLink id="toggler" type="button" />
<p:columnToggler datasource="#{cc.attrs.tableID}" trigger="toggler" />
<p:commandLink id="exportToXLS" ajax="false" width="24">
<p:dataExporter type="xls" target="#{cc.attrs.tableID}"
fileName="fileXls" />
</p:commandLink>
</composite:implementation
Here is github repo with project with code where my problem occur: https://github.com/ntokarsk/PrimefacesTest

Problem solved.
I still don't know why previous solution didn't work - but this solution works. I have just read some old post and learn that menuitem is commandLink itself so I move p:dataExporter into menuItem and it works :D
1 thing is still missing - columnTrigger doesn't work. Any idea?
here's the code:
<composite:interface>
<p:menuitem value="Export to XLS" ajax="false">
<p:dataExporter type="xls" target=":#{cc.attrs.FormID}:#{cc.attrs.tableID}"
postProcessor="#{edycjaDanychCentrumBean.postProcessXLS}"
fileName="daneCentrumDataTable" />
</p:menuitem>
<p:menuitem value="Export to PDF" ajax="false">
<p:dataExporter type="pdf" target=":#{cc.attrs.FormID}:#{cc.attrs.tableID}"
fileName="daneCentrumDataTable" />
</p:menuitem>
</p:submenu>
<p:menuitem value="Delete" icon="ui-icon-close" />
<p:menuitem id="toggler" value="Columns" icon="ui-icon-calculator">
<p:columnToggler datasource=":#{cc.attrs.FormID}:#{cc.attrs.tableID}" trigger="toggler" />
</p:menuitem>
</p:contextMenu>
</composite:implementation>
