it seems this.statesub undefined if there working subscribe ???

what doing wrong ???

thanks

in template events, this binds context document (in impressive ways sometimes) can this._id document in "html scope" event took place.

if want persist object throughout events, can use template object event receives argument instead. object persist across events, long you're on same template, is.
