setSelected: function(selected){            for (var i = 0; i < selected.length; i++){                var value = selected[i]; var b = this.textboxlist.create('box', value.slice(0, 3)); if (b){ b.autoValue = value; if (this.index != null) this.index.push(value);                        var afterEl = this.textboxlist.list.getLast('.' + this.textboxlist.options.prefix + '-bit-box'); b.inject(afterEl || this.textboxlist.list, afterEl ? 'after' : 'top'); }            }        },

I had problems at showResults:
if (this.index) results = results.filter(function(v){ return !this.index.contains(v); }, this);

so id changed that line by 

                if(this.index.length){                    var resultsok = [];                    for (var i = 0; i < this.index.length; i++){                        for (var j = 0; j < results.length; j++){                            if(this.index[i][0] != results[j][0]){                                resultsok.push(results[j]);                            }                        }                    }                    results = resultsok;                }

hope this can help
