How to bind a checkbox list using AngularJS and get all selected value from the checkbox using ng-reapet method?

I am try to get the value of the selected check box in the angular controller.

View

<ul class="to_do">
    <li ng-repeat="form in ManagementScreenModel.Forms">
        <!--<input type="checkbox" ng-model="RoleData.formUrl" value="{{form.Value}}" id="{{form.Value}}">-->

        <input type="checkbox"
               ng-model="RoleData.selectedForms"
               data-checklist-model="RoleData.ManagementScreenModel.Forms"
               data-checklist-value="{{form.Value}}"
               id="{{form.Value}}">

        {{form.Text}}
    </li>
</ul>

Controller

$scope.SetUserpermision = function() {
    Get(
        "/Home/GetAvailableForms",
        null,
        function(result) {},
        function(result) {
            userforms = result;
            //$scope.GetUserForms = json.parse(result);
        },
        null
    );

    Post(
        "/ManagementScreen/SetAccess",
        $scope.RoleData.userforms,
        function OnError(jqXHR, testStatus, errorThrown) {
            // display error here
        },
        function (result) {
            var response = JSON.parse(result);
            if (response != null && response.StatusCode === 200) {
                //alert("User email change successfully");
            }
        },
        null
    );
}

Have a boolean variable in ManagementScreenModel.Forms (like 'checked') and after submitting the form check variable the entry is checked or not.

<md-checkbox ng-model="user.checked" aria-label="Checkbox 1"></md-checkbox>

    angular.forEach($scope.users, function(user, i) {
     if(user.checked === true){
//store in an array
}
});
