Checkboxlist ng-repeat filter dynamic angularjs

I am trying in AngularJS to display the employee details with dynamic filter (Location - Value like US, IN, CA etc..) as checkboxlist based on the data got it from DB. I have tried multiple ways without success. Please help to achive the dynamic filter from Checkboxlist.

My code sample below:

  <html>
<body ng-app="myapp" ng-controller="myController">


     <div >Location</div>
        <table>
            <tbody>
                <tr ng-repeat="empL in EmpResult | unique : 'Location'">
                    <td>
                        <span>
                            <input type="checkbox" ng-model="loc" value={{empL.Location}} />
                            {{empL.Location}}
                    </span>
                </td>
            </tr>
        </tbody>
    </table>
    <table align="left" style="width: 100%" class="table">
        <thead>
            <tr>

                <th align="left" style="width: 30%">Employee</th>
                <th align="left" style="width: 20%">Address</th>
                <th align="left" style="width: 15%">Location</th>
            </tr>
        </thead>
        <tbody>
            <tr ng-repeat="empN in EmpResult | filter : loc">

                <td align="left" style="width: 30%">{{empN.EmpName}}</td>
                <td align="left" style="width: 10%">{{empN.Address}}</td>
                <td align="left" style="width: 15%">{{empN.Location}}</td>

            </tr>
        </tbody>
    </table>

    <script type="text/javascript">

        var myapp = angular.module('myapp', ['ui.unique'])
        .controller("myController", function ($scope, $http) {

            $http({
                method: 'Get',
                params: { strName: $scope.strName },
                url: 'Emp.asmx/GetEmpbyName'
            }).then(function (response) {
                $scope.EmpResult = response.data;
            })

        });
    </script>
</body>
</html>

This code will display all the values if none of the checkbox is selected.

<tr ng-repeat="empN in EmpResult | filter : 'loc'">

Use the filter with single quotes also. This will filter the data from checkbox.
