I have datepicker code is this..

$("input[id^='exc-flwup-']").datepicker({
            duration: 0,
            constrainInput: true,
            showTime: true,
            stepMinutes: 30,
            stepHours: 1,
            altTimeField: '',
            time24h: true,
            minDate: 0
        });

Input field is

 <label for="FollowupDate">
            Follow-up:
            <input type="text" id="exc-flwup-<%=Model.ExceptionID %>" name="exc-flwup-<%=Model.ExceptionID %>" value="<%=Model.FollowupDate %>" />
        </label>
