My way to solve this problem

Change var 'controls' on ui.js

controls = (!inst.inline ? "<button type='button' class='ui-datepicker-close ui-state-default ui-priority-primary ui-corner-all' data-handler='hide' data-event='click'>" +
        this._get(inst, "closeText") + "</button>" + "<button type='button' class='ui-datepicker-close ui-datepicker-clear ui-state-default ui-priority-primary ui-corner-all' data-handler='hide' data-event='click'>" +
        this._get(inst, "clearText") + "</button>" : "");

Then add a clearText var

    this.regional[""] = { // Default regional settings
    closeText: "Done", // Display text for close link
    clearText: "Clear", // Display text for close link
    prevText: "Prev", // Display text for previous month link

And before show function

$(".i_date").datepicker
(
    {
        beforeShow: function (input, inst)
        {
            setTimeout
            (
                function () 
                { 
                    $('.ui-datepicker-clear').bind('click', function() { $(input).val(''); });
                }, 
                0
            );
        }
    }
);

Try changing the clearing code to:

$('#clearDates').on('click', function(){
    dates.attr('value', '');
    $("input[id$='dpFrom'], input[id$='dpTo']").datepicker( "option", "maxDate", null );
    $("input[id$='dpFrom'], input[id$='dpTo']").datepicker( "option", "minDate", null );
});

Try This, This Will Add Clear Button On Jquery Calender That Will Clear Date.

$("#DateField").datepicker({
    showButtonPanel: true,
    closeText: 'Clear',
         onClose: function (dateText, inst) {
        if ($(window.event.srcElement).hasClass('ui-datepicker-close'))
        {
            document.getElementById(this.id).value = '';
        }
    }
});

A modified version of Leniel Macaferi's solution to account for the backspace key being a "page back" shortcut in IE8 when a text field does not have focus (which appears to be the case when datepicker is open).

It also uses val() to clear the field since _clearDate(this) did not work for me.

$("#clearDates").datepicker().keyup(function (e) {
    // allow delete key (46) to clear the field
    if (e.keyCode == 46)
        $(this).val("");

    // backspace key (8) causes 'page back' in IE8 when text field
    // does not have focus, Bad IE!!
    if (e.keyCode == 8)
        e.stopPropagation();
});

$("#datepicker").datepicker({            
        showButtonPanel: true,
        closeText: 'Clear', 
        onClose: function () {
            var event = arguments.callee.caller.caller.arguments[0];                
            if ($(event.delegateTarget).hasClass('ui-datepicker-close')) {
                $(this).val('');
            }
        }
    });
