Cannot change variable nested properties

[amankapur]

var foo = "apple";

var model = new Model({
    name: 'test',
    bar: {
      apple: 1,
      banana: 2
    }
})

model.set('bar[foo]', 'orange') fails. and so does model.remove('bar[foo]')

I understand that is tricky and is getting into string pramming limitations, but is there a simple workaround?

thanks

get is easier model.get('bar')[foo]

Did you mean model.set('bar[' + foo + ']', 'orange')?
