Notepad++ regex replace - how to remove this string -

I want to remove the wire as the following where some-less text is a random text string .

  $ ('#te-lesson'). Val ();  

I have tried many things, but I think the $ symbol is messing up because it is used in regedx.

You need to avoid some characters.
Try it -

  \ $ \ ('# [^'] * '\) \ val \ (\).
