How to Change Certain Language Strings

I need to change two strings but don't have success as follows:

First, I have changed these language strings:
1) JUX_TESTIMONIAL_VIEW_MORE Load more endorsements
2) NOO_THEME_VIEW_MORE Load more endorsements

But Testimonial still shows "Load more Testimonial +" on the site.

Second, I can't find the string "No data more" which is displayed if you hit the "Load more Testimonial +" button and there is no more data.

Thanks,
