Primefaces commandbutton clientside variable

I'm migrating richfaces to primefaces. 

<a4j:commandButton id="editStatusButtonId" 
data="#{userTO.emailIdMandatoryStatus}" action="#UserAdministration.editStatusButtonAction}" oncomplete="if(data=='#{UserAdministration.configureEmailSettingStatus}')/>

I need any replace attribute for data in primefaces commandabutton.

It comes as the callback parameter in primefaces, on the RequestContext component.

I'm going to "borrow" generously from the manual.

From your backing bean:

RequestContext requestContext = RequestContext.getCurrentInstance();
requestContext.addCallbackParam("mandatoryStatus", userTO.emailIdMandatoryStatus); //isValid is the parameter

In your page, likely in a js function:

var mandatoryStatus= args.mandatoryStatus;

It has almost exactly the same semantics as in RF; the values are serialized as JSON, just as in RF; the data is made available on the args object, in RF - the event.data

Putting it all together, you can have:

<p:commandButton id="editStatusButtonId" action="#{UserAdministration.editStatusButtonAction}" oncomplete="if(args.mandatoryStatus=='#{UserAdministration.configureEmailSettingStatus}')/>
