How can i go about adding a custom module to models.js to load ? and how can i gte my js file to read a new js function
so far i have created a js file which as the same content as models.js called pos_extend.js and created a new function however it seems my file is not being read.
and i get this error : Uncaught Error: QWeb2 - template['PosTicket']: Runtime Error: TypeError: undefined is not a function
static/src/js/pos_extend.js :
