Problem with select ng-option and ng-change

I have some problem with ng.options, after i have populated it with db callback, if i try to change selected option i receive ever the first element, in the inspector i can see the selected option don’t switch, but in view if i add {{modelName.value}} i can see the right value, but in controller it don’t update.

Thanks Claudio

You probably should put up a sample demo we can take a look at.

Sorry, it’s my mistake on the controller… i have solved it… thanks
