Not able to update "growl" in template from Backing bean

I have a template file which contains primefaces growl component. I am using this template in another index.xhtml file. Now I am trying to add a FacesMessage from backing bean in @postconstruct function. However my index.xhtml file is not showing the growl.

template.xhtml

       <div id="content-wrapper">
            <div id="content" class="template-00-startpage clearfix">                  
                <p:growl id="growl" showDetail="true" sticky="true" />             
            </div>
        </div>

index.xhtml

<h:body>
    <ui:composition template="/templates/Template.xhtml">
        <ui:define name="leftContent">
            <h:outputText value="#{backingBean.username}"></h:outputText>
        </ui:define>
    </ui:composition>
</h:body>

backingBean.java

@PostConstruct
private void init(){
    username = "testing it";
    FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO, "Info", "Trying to display this message");
    FacesContext.getCurrentInstance().addMessage(null, msg);
    RequestContext requestContext = RequestContext.getCurrentInstance();
    requestContext.update("growl");      
}

I tried wrapping the <p:growl> component in <h:form id="main"> and then update main:growl, however it does not work.

I am not understanding what I am doing wrong. Is it necessary to trigger or update growl in .xhtml file or via commandButton?
