When displaying a series of values from an array, the data items are not being bound to the model properly, as in:

$scope.model = {  values: [    "Value 1",    "Value 2,    ...  ]}

If the above is displayed in a series of input fields, changes to the content are not reflected in the model. However, binding the above using code like the following does maintain binding to the model:

<div ng-repeat="value in model.values">  <input type="text" ng-model="model.values[$index]" /></div>

However the issue with this approach is that the text field loses focus on each keyup. A demo is here:
