Adding command button in p:schedule header - jsf

Question

How do i add a "custom" button in p:schedule? I tried doing it with the help of a header facet like in the p:dataTable component, but to no avail.
Sorry for being unclear initially, it also probably didnt help that someone butchered my question by editting it's title, here are more details with snippets of code.
I want to do somthing similar to this:
<p:tab title="#{bean.name}" value="bean" >
<f:facet name="title">
<h:outputText value="#{bean.name}"/>
<p:selectBooleanButton styleClass="...">
<p:ajax converter="... />
</p:selectBooleanButton>
</f:facet>
</p:tab>
The code is creating a tab (for an accordionpanel) with a text+button in it instead of the default text only.
I am looking for the same behaviour in a p:schedule component.
<p:schedule value="#{scheduleView.lazyEventModel}" leftHeaderTemplate="today" centerHeaderTemplate="prev, title, next" rightHeaderTemplate="month, agendaWeek" >
<f:facet name="header">
<h:outputText value="#{bean.name}"/>
<p:commandButton styleClass="..."/>
</f:facet>
</p:schedule>
The same add a button to the header principle, except this time on schedule. And of course since schedule does not have any facets available for overwriting this approach does not work.
Finally, my question is: How do I add a button in the p:schedule header like in the picture above?
P.S: Forgive me for confusing you people with datatable, used it because it supports multiple facets (header, footer).

Client side it is all html that can be manipulated with javascript (jquery if you like).
So if you create your schedule and button like this:
<h:panelGroup id="mySchedule">
<p:schedule value="#{scheduleView.lazyEventModel}" leftHeaderTemplate="today" centerHeaderTemplate="prev, title, next" rightHeaderTemplate="month, agendaWeek"/>
<h:outputText value="#{bean.name}" id="scheduleOutputText"/>
<p:commandButton styleClass="..." id="scheduleCommandButton"/>
</h:panelGroup>
You can move the h:outputText and p:commandButton into the schedule with jquery dom manipulation.
$("#scheduleCommandButton").insertBefore(".fc-left");
$("#scheduleOutputText").insertBefore("#scheduleCommandButton");
If you put this script inside the panelGroup and update the panelGroup each time you'd normally update the schedule via ajax, the button and text should be added moved again in an update.
<h:panelGroup id="mySchedule">
<p:schedule value="#{scheduleView.lazyEventModel}" leftHeaderTemplate="today" centerHeaderTemplate="prev, title, next" rightHeaderTemplate="month, agendaWeek"/>
<h:outputText value="#{bean.name}" id="scheduleOutputText"/>
<p:commandButton styleClass="..." id="scheduleCommandButton"/>
$("#scheduleCommandButton").insertBefore(".fc-left");
$("#scheduleOutputText").insertBefore("#scheduleCommandButton");
</h:panelGroup>
You could also put the text and button in a panelgroup and move that by dom manipulation. Just make sure you use the right selectors (I did not prepended the form id to the selectors above). You can also use class selectors instead of id's. That is up to you.
But make sure you use this with care. As #JasperDeVries mentioned in a comment, it is easy to break things. Use it just sparsely, carefully and only as a last resort
