as explained here Binding inputs to an array of primitives using ngRepeat => uneditable inputs, yes you can, but not that way
try this
function ctrl($scope) {
$scope.arr = [{name:'1', lastname: '2'},
{name:'3', lastname: '4'},
{name:'5', lastname: '6'}]
}
<div ng-repeat="person in arr">
<input type="text" ng-model="person.name" />
<input type="text" ng-model="person.lastname" />
</div>
