Answer 1

Result of this code: items.split(',') is an array that does not exists in scope, so it cannot be a writable model for ng-repeat directive. You should create an array in your scope like this:

$scope.items = (JSON.stringify(data[0].D_Services).replace(/\"/g, "")).split(',');

and use this model in markup

<div ng-repeat="item in items">
    ...
</div>

If you need result as a string, you should join it before returning:

$scope.check = function(items) {
   console.log(items.join(','));
};

Answer 2

since items is an string like

var items = "john,grace,peter";

and when you perform items.split(',') it will result and array of strings like

["john","grace","peter"]

and when ng-model trys to set checked status for each element which is error because you can't do operations like

items[1].selected

since items[1] is an array.
