Bootstrap date picker end date is not working

$("SELECTOR").datepicker({
 autoclose: true,
 todayHighlight: true,
 format: {
      toDisplay: function (date, format, language) {
           return moment(date).utc().format(format1);
      },
      toValue: function (date, format, language) {
           var date1 = moment(date).format('YYYY-MM-DD');
           var d = new Date(date1);
           d.setDate(d.getDate() + 0);
           return new Date(d);
      }
 },
 language:"en",
 endDate: '+0d'});

Here due to format code the end date is not working, and I can not remove that too, I want to disable all the future dates with this code, please suggest any solution.
