Backbone.js Collections do not invoke "Reset" event after fetch operation
You should tell Backbone to fire the reset on fetch by passing {reset: true} when fetching as of Backbone 1.0
Replace :
Theater.movies.fetch()With
Theater.movies.fetch({reset :true})
There might be a problem with your fetch if the collection is not being populated. See this answer to see how to pass an error handler into the fetch operation.
I had a similar issue, I hope my reply will be of any use to others. At first my data.json file was not valid. Then it turned out that I overlooked the following line of code:
Theater.Models.Movie = Backbone.Model.extend({}Adding this line of code resolved the issue for me.
