Dynamically add results without reinitiating the typeahead

Is there a way to dynamically add new content without reinitiating the typeahead?

For instance, a specific usecase, I need to show a result that is dependent on the user input. For instance, if the typeahead value is "something", I need to display a result, where the datum.value is "bla bla something"

Seems mentioned here as well: https://github.com/corejavascript/typeahead.js/issues/161
