How can I add dropzone result to angularjs input?

[aydcery]

In my Angular app I am using DropzoneJs to upload images in ng-repeater field , everything working fine I can upload images to my server and I can get Json results , But I need to add uploaded image id to angular input value ,

Here my angular code

Dropzone.autoDiscover = false;
var app = angular.module('dropzone', []);
app.directive('dropzone', function() {
	return function(scope, element, attrs) {
		var config, dropzone;
		config = scope[attrs.dropzone];
		// create a Dropzone for the element with the given options
		dropzone = new Dropzone(element[0], config.options);
		// bind the given event handlers
		angular.forEach(config.eventHandlers, function(handler, event) {
			dropzone.on(event, handler);
		});
	};
});
angular.module('plunker', ['ui.sortable', 'dropzone']);
angular.module('plunker').controller('MyCtrl', ['$scope', function($scope) {

	$scope.inputs = [{
		choices: ''
	}];
	$scope.addInput = function() {
		$scope.inputs.push({
			choices: ''
		});
	}

	$scope.dropzoneConfig = {
		options: {
			'url': 'upload.php',
			init: function() {
				this.on("success", function(file, response) {
					var e = JSON.parse(response);
					console.log("sent" + e.location);
					$scope.inputs.img = e.location;
					
				});
			}
		},
	}
}]);

and here html code;

<div class="inputArea" ng-controller="MyCtrl" ng-app="plunker">
		<div ui-sortable="sortableOptions" ng-model="inputs" >
			<div ng-repeat="input in inputs" >

		<div ng-model="input.files" id="dropzone1" class="dropzone " dropzone="dropzoneConfig" ng-dropzone></div>

    <label for="imgid">ImageID:</label>
		<input id="imgid" type="text" ng-model="input.files.img" name="out[{{$index+1}}][img]" autocomplete="off"/>
    <p></p>
<label for="desc">Description:</label>				
	<textarea id="desc" type="textarea"  name="out[{{$index+1}}][desc]"></textarea>

		</div>
		</div>
		<div class="add-poll" ng-click="addInput()">add input</div>
	</div>

I tried this;

$scope.inputs.img = e.location;

but not working , here Plunker
