Set year of datepicker using jquery

I am doing some work in .net technology using MVC 4.0 with VB language.

I have dropdownlist that has a set of years from 2006 to running year. I want to set the selected year from dropdownlist to datepicker so I can have that year specific months and days and I have done following changes in datepicker.

 $('input').filter('.datepickerHoliday').datepicker({
                            changeMonth: true,
                            changeYear: false,
                            showYear: false,
                            dateFormat: 'mm/dd/' + yr,
                        });

How can I do this?
