Datepicker minDate with StartDate

What I am trying to do with datepicker is when it first shows, display the current date plus 6 months, which you can do with startDate, but the month back button is disabled. I tried to set a minDate for todays date, same deal, month back button is disabled.

Is there away to have the start date to be the current date plus 6 months, but allow users to click the month back button and not allowed to go past the current date.

var date = new Date();
                date.setDate(date.getDate() - 1);
                var defaultDate = new Date();
                defaultDate.setMonth(date.getMonth() + 6);

                $('[data-toggle="datepicker"]').datepicker({
                        format: 'dd/MM/yyyy',
                        autoHide: true,
                        minDate: date,
                        startDate: defaultDate,
                        changeMonth: true
                });
