Not sure if this is a bug or just me

NodeJs, Docker project, dealing with a server action, I would like to add a where() formatter, in the UI it is doing it like this

{{tstC.where('image_type', '==', ism_type)}}

I find it strange because image_type and ism_type are both dynamic values and both being picked from database multi queries, this is reading to me like one is a string and the other a dynamic value.

I tried this

{{tstC.where(`image_type`, '==', `ism_type`)}}

Which I always thought was correct, using backtick, but I get a lexar error of unexpected token
