Tab out of knockout datepicker

Need to add this to the data-bind parameters:

onClose: function(dateText) {
$(this).focus();
}

example:

<input style="float:left;" placeholder="Date of Birth" id="studentDOB" class="textAnswer datepickerDOB" type="text" 
    data-bind="datepicker: {
            onClose: function(dateText){$(this).focus();},
            changeMonth:true,
            changeYear:true,
            yearRange: '-25:c'},
    value : studentDOB, valueUpdate: 'input'" />
