How to update typeahead when fetching new data?

In 0.1.11 there was an "update" method for the typeahead instance, in 1.2.0 this method was removed from the source.

I am updating request string on custom click (adding some custom params, but the query is same) and fetching new data from server.
Before i just called "update" method with force:true

`$(selector).typeahead('update', true)`

Now i am at loss with this situation, i can call search from Bloodhound with query string and custom parameters on prefetch, but i need to reload typeahead dropdown result data at all.

```
var bloodhoundOptions, opts, typeaheadopts;
bloodhoundOptions = {
remote: {
url: this.options.accountsUrl,
prepare: _prepareRequest.bind(this),
transform: _transformResult.bind(this),
rateLimitWait: 500
}
};
this.driver = Typeahead.createBloodhound(bloodhoundOptions);
typeaheadopts = {
minLength: 2,
hint: false,
highlight: true
};
opts = {
display: 'text',
source: this.driver,
limit: Number.MAX_VALUE,
templates: ...........
};
```

```this.widgetTh = new Typeahead(selector, typeaheadopts, opts);```

```
var async, sync, query;
sync = (function(_this) {
return function(data) {};
})(this);
async = (function(_this) {
return function(data) {
_this.driver.add(data);
????? How to update typeahead ????
};
})(this);
return this.driver.search(query, sync, async);
```

Is there a way to force update typeahead with new data without reinitializing and destroying current widget instance?
