JSF :: How To Access A Method With Session Scope Via Hyperlink

I have a hyperlink say,

[URL]

now, i want to access a managed bean's method to execute a service call related to the code embedded in the hyperlink.

My Managed bean

@ManagedBean(name="details")
@SessionScoped
public class XXXX extends Bean implements Serializable{
public XXXX(){...... }
public myMethod(..){
service.getDataRelatedToHyperlinkCode(....passing code here to fetch details from DB)
}
}

if i use postConstruct annotation it is getting executed only once since it is a session scope. and point to be noted is i cannot use viewscope and requestscope.
