How to show NUMBER OF VIEWS in modules?

How to show NUMBER OF VIEWS for each priperty in RandomPropertiesModule and ContentsliderModule?
Please explain which code and where to insert !

Hi Konstantin,
Currently, 2 that modules don't have feature to show number of views for each property. We don't have details document, but you can modify them at:
Random properties module:
root > modules > mod_ospropertyrandom
Content slider module
root > modules > mod_os_contentslider
Thanks
Dam

Thanks! But how to modify them? What expression (code) I have to use for "number of views" in these modules ?
