Store the value of Checked checkbox in a variable using Angular JS

I have created group of checkbox using ng-repeat using the below days object value.

$scope.config = { days: [
             {name:'Monday'},
             {name:'Tuesday'},
             {name:'Wednesday'},
             {name:'Thursday'},
             {name:'Friday'},
             {name:'Saturday'},
             {name:'Sunday'},
        ]}
});

My checkbox using ng-repeat is like that.

<ul class="list-inline">
<li ng-repeat="day in config.days">
    <div class="checkbox">   
        <label class="xsm-label">
            <input type="checkbox" ng-model="day.selected" value="" id="cs_select_" name="selected_days" />&nbsp;
        </label>
    </div>
</li>
</ul> 

I tried much but no luck, kindly help me how to store value of checked checkbox value in a variable.

Thank you.
