I am using Prism in an application and I need a way to run call a function every time a module is requested. The thing is that this function will query the database for some items, and I need to do this every time the module is requested by pressing the module item buttom from a menu. I tried adding this to the constructor, but the problem is that the constructor is called during the initialization of the application from the bootstrap!

Is there a simple way to do this?
