Attach events to the Widget lifecycle so you can call client side Javascript during PostConstruct, PostRefresh, or PreDestroy of the widget.
<div class="card">

<p:inputText id="name" value="#{lifecycleView.text}" widgetVar="wgtName">
<f:attribute name="widgetPostConstruct" value="PF('msgs').renderMessage({severity: 'info', summary: 'Widget Created'})"/>
<f:attribute name="widgetPostRefresh" value="PF('msgs').renderMessage({severity: 'info', summary: 'Widget Refreshed'})"/>
