You should first import the models using this statement:
var models = require('point_of_sale.models'); Then you can alter a specific function using:
models.TheWidgetThatContainsTheFunction.include({
the_function_to_modify: function(){        //don't forget to include function vars!
this.super();
// ... do stuff here
// return if necessary
},
});
