Error when there is a dash in field name

[mohsen1]

If my model has property with dash in it, I will get the following errors.

Error: [ngModel:nonassign] Expression 'model.X-Test' is non-assignable. Element: <input ng-show="form.key" type="{{form.type}}" step="any" sf-changed="form" placeholder="{{form.placeholder}}" class="form-control" ng-model-options="form.ngModelOptions" ng-model="model.X-Test" ng-disabled="form.readonly" schema-validate="form">

From what I see, it's trying to access model.X-Test which is invalid JS. From my little research it could be related to $$value expression here

Hey @mohsen1, there is a bug in Angular 1.2 that makes this impossible, but this works perfectly if you're on Angular 1.3

[mohsen1]

Thanks @mike-marcacci Upgrading to 1.3 fixed this. I needed a good incentive to take the time and upgrade. This did it!

[mike-marcacci]

Awesome, glad it worked!

Not working in form binding. I am using <select ... ng-model="staff.member-Type">. But still facing same issue. what could be the possible solution. As JSON format cant be changed.

@ajit-drag you need to make a plunker or gist or provide exampes if you want people to understand your issue.
