set checkbox as checked/unchecked based on database jQuery

I am trying to set data on localStorage as 1/0.Then if I get 1 from it I want to checked a checkbox else unchecked.I was wrote a code but it isn't working.And I can't find-out what I am doing wrong!

<label class="a-b-c">
  <input id="check-it" type="checkbox" name="check">
  Check.
</label>

$(window).load(set_func_o());
    function set_func_o(){
        try_it();
        $('#check-it').change(function(){
            var chk= this.checked ? '1':'0';
            localStorage.setItem('checkit-the-item',chk);
            try_it();
        });
        function try_it(){
        var check_stat= localStorage.getItem('checkit-the-item');
        check_stat === '1' ? $('#checkit').prop('checked',true):$('#checkit').prop('checked',false);
        }
    }

Suggestion please!
