Button "more information" with modal window to show post content

hello, I created a new template in the “Search Results Layout”. Adding a button called More Information that opens a window with the content of the post/coupon. However, the shortcode [CONTENT] and [TITLE] are not displaying content related to the post that the person is clicking, but yes, always the information in the first post. Does anyone know how to resolve this?
