Change "older" and "newer" text

Hi,
I made a child theme and now I would like to change those “Older Posts” and “Newer Posts” to my own language (Finnish). I found the file from the parent theme (highwind/framework/highwind-template.php), but when I copied the path (highwind-child/framework/highwind-template.php) and changed the text there, it didnt show up. I also tried to copy whole framework-folder but no changes.

It did show up when I modified it in parent-theme. However, I dont want to modify the original theme so I would appreciate help ??

Thanks!
