You are using not correct quotes:

 $(document).ready(function(){

        var priceModal = "{'attributes':{'Code':'DBL','Total':'200000'},'DayPrice':{'Date':'2016-05-26','Rate':'200000'}}";

        var isitable="<button class="btn blue tes_button" data-toggle="modal" data-target="#priceModal" id="priceModal"+priceModal+'">tes</button>';

        $("#tes").html(isitable);
        $('#priceModal').on('show.bs.modal', function(e) {
            var param = e.relatedTarget.id;
            console.log(param);
        });
    });
