Ember.js : cannot make one-way bindings work

Question

I have a template who is iterating on a list of numbers and create a form. I don't want the changes made to the forms propagated to the underlying values, therefore, i am using a one way-binding.

Unfortunately, it doesnt't seems to work : JSBin

Thanks you a lot !

Answer 1

Your problem is that the Binding is setup at the "list" level, so the oneWay binding does not apply to specific items and their properties.

Instead of a oneWay binding, you can create a computed property which generates a new copy of your list.
