How do I put a data binding where a string is expected?

I need to put a data binding variable in an attribute.

The attribute is data-vimeo-id=" "

It’s expecting a number like: 12839238

This number is in a variable: {{get_lecture_video.data.get_lecture_video[0].lecture_vimeo_id}}

But I can’t put it in there, I guess I should be escaping it. But I’m not sure how…

Please help
