        //keyboard support
        $(document).off('focus.ui-chkbox blur.ui-chkbox keydown.ui-chkbox keyup.ui-chkbox', checkboxInputSelector)
                .on('focus.ui-chkbox', checkboxInputSelector, null, function() {
                    var input = $(this),
                    box = input.parent().next();

                    if(input.prop('checked')) {
                        box.removeClass('ui-state-active');
                    }

                    box.addClass('ui-state-focus');
                })
                .on('blur.ui-chkbox', checkboxInputSelector, null, function() {
                    var input = $(this),
                    box = input.parent().next();

                    if(input.prop('checked')) {
                        box.addClass('ui-state-active');
                    }

                    box.removeClass('ui-state-focus');
                })
                .on('keydown.ui-chkbox', checkboxInputSelector, null, function(e) {
                    var keyCode = $.ui.keyCode;
                    if(e.which == keyCode.SPACE) {
                        e.preventDefault();
                    }
                })
                .on('keyup.ui-chkbox', checkboxInputSelector, null, function(e) {

                    if(e.which == keyCode.SPACE) {
                        var input = $(this),
                        box = input.parent().next();

                        if(input.prop('checked')) {
                            _self.unselectRowWithCheckbox(box);
                        } 
                        else {                        
                            _self.selectRowWithCheckbox(box);
                        }

                        e.preventDefault();
                    }
                });
