Datepicker is displayed when using "setDate" and "change" method

To fix this problem, do not call _updateDatepicker() in _setDateDatepicker() and _changeDatepicker():

_changeDatepicker: function(target, name, value) {

var settings = name || {};

if (typeof name == 'string') {

settings = {};

settings[name] = value;

}

if (inst = $.data(target, PROP_NAME)) {

extendRemove(inst.settings, settings);

to remove===> this._updateDatepicker(inst);

}

},

_setDateDatepicker: function(target, date, endDate) {

var inst = $.data(target, PROP_NAME);

if (inst) {

this._setDate(inst, date, endDate);

to remove===> this._updateDatepicker(inst);

this._updateAlternate(inst);

}

},
