Module and Menu Assignment

Hi every body,
I use an event management component.
I have a module in the SIDEBAR position (a calendar). When i click in a date of the calendar, a new page appared in the MAIN BODY = ok.
The problem is that my module calendar disappears from the right position when the page is loaded.
I can not assign a menu as the URL of the page loaded is not a menu entry.
The URL is "http://localhost/association/index.php/component/jem/day/20161109"
I do not create a menu item to bring up my module because I do not know in advance the URL
I have attached 2 image to illustrate.
Thanks for your help. I hope you can help me.

Hi

Unfortunately joomla requires to have the page module is displayed specified. All I can advice in this case is to set the module to show on "All pages" or "Everywhere except" and select pages where it should not be visible for sure.
