Hello,
It also happens to me, I've fixed it by adding this:

          
            var data = {};
            var value = this.$element.val();
[COLOR=#008000][B]            if (value == null) {
                value = $("input[data-name='"+this.name+"']").val()
            }[/B][/COLOR]

            if (this.params.trim || this.forceTrim) {
                if (typeof value.trim === 'function') {
                    value = value.trim();
                }
            }

            data[this.name] = value || null;
            return data;
