        <input ng-model="data" />
        <div ng-controller="innerCtrl">
            <input ng-model="data" />
        </div>
        <div ng-controller="innerCtrl">

angular.module('myApp', [])
.controller('outerCtrl', function($scope) {
    $scope.data = 123;
})
.controller('innerCtrl', function($scope) {
    $scope.reattach = function() {
        delete($scope.data);
    };
});
