If you want to call javascript before calling server, use onsubmit="javascriptcode". After calling server - oncomplete="javascriptcode".

Both the event i have to write in a4j:support ?
like this stucture....

<h:selectBooleanCheckbox>
<a4j:support event="onchange" immediate="true" onsubmit="callJsFuction" oncomplete="#{bean.serverMethod}">
</a4j:support>
</h:selectBooleanCheckbox>
