Backbone - merge: true - option not changing UI

I noticed that when I write

collection1.add(model1); --> UI changes fine. However, when I do
collection1.add(model1, {merge: true});
then App.div1.currentView.collection.models shows the changed model (in console) but UI does not change.

I have no clue why?

(Note1: I am using Marionette.js with Backbone)
(Note2: App is the global Marionette object; div1 is a Marionette region in html)

Solution

  • This is what worked with collection1.add(model1, {merge: true}) - 

    modelEvents: {
    "change": "render"
}

// "update": "render" did not work

    Added ^^ to Marionette.ItemView which was responsible for model1.
