executing code before an autoform update

[ZHosseinpour]

I want to do something before an autoform update occur . i use ' coll.before.update ' to execute my logic in its function but the callback function dos not execute even though the update occur . i don't know where i made mistake or if anything else i should do. this is my code:

ads.before.update(function(userId, doc,fieldNames, modifier, options) {
 console.log("doc");
 doc.img = Session.get("imgAds");
 // doc.linkItem=Session.get("itmId")
 });
