Call jQuery function when rendering component via ajax

Question

I have a little problem that is:

I have a component RichFaces more specifically the rich:listShuttle id "migrarId". Inside that component I have a input who owns a placeholder that is generated via jQuery every time the page is loaded.

The problem is that input has a ajax with the event "onkeyup" that when I type and delete something he reRenderize the entire component of rich what ends up doing the placeholder disappear.

`<h:inputText styleClass="filtroOrigem" id="filtroOrigem" value="#{migrarUsuarioManagedBean.filtroOrigem}">
 <a4j:support requestDelay="1000" event="onkeyup" ajaxSingle="true" process="filtroDestino" action="#{migrarUsuarioManagedBean.filtrarDestino}" reRender="migrarId" />
</h:inputText>`

    $(document).ready(function() {
            $('input.filtroOrigem').attr("placeholder", "Digite Chave, Nome ou Unidade");
    });

I was wondering if there’s any way to generate the placeholder whenever this component is rendered via ajax not when the page is loaded.
