You can use:

var rep = item.label.replace(exp,
                             "$&");

When replacing a string, $& means "the whole match", so you don't have to repeat the search term (in some cases you don't know it). In other flavors, you may use $0 or \0.
Also, remember to escape special characters in this.term.
