Ion menu not work

Good afternoon,
I need that every time the ion-menu opens, it shows me different data, but since it is loaded at the start of the application, no matter how hard I try, I don’t get it.
I have tried using two menus, one I add directly to the page where I need to make the query, so far so good, but when I go back, the main menu stops showing.
Any ideas?

Thanks in advance
