Custom EventsThe following events get triggered on the input element during the life-cycle of a typeahead.typeahead:active  Fired when the typeahead moves to active state.typeahead:idle  Fired when the typeahead moves to idle state.typeahead:open  Fired when the results container is opened.typeahead:close  Fired when the results container is closed.typeahead:change  Normalized version of the native change event. Fired when input loses focus and the value has changed since it originally received focus.typeahead:render  Fired when suggestions are rendered for a dataset. The event handler will be invoked with 4 arguments: the jQuery event object, the suggestions that were rendered, a flag indicating whether the suggestions were fetched asynchronously, and the name of the dataset the rendering occurred in.typeahead:select  Fired when a suggestion is selected. The event handler will be invoked with 2 arguments: the jQuery event object and the suggestion object that was selected.typeahead:autocomplete  Fired when a autocompletion occurs. The event handler will be invoked with 2 arguments: the jQuery event object and the suggestion object that was used for autocompletion.typeahead:cursorchange  Fired when the results container cursor moves. The event handler will be invoked with 2 arguments: the jQuery event object and the suggestion object that was moved to.typeahead:asyncrequest  Fired when an async request for suggestions is sent. The event handler will be invoked with 3 arguments: the jQuery event object, the current query, and the name of the dataset the async request belongs to.typeahead:asynccancel  Fired when an async request is cancelled. The event handler will be invoked with 3 arguments: the jQuery event object, the current query, and the name of the dataset the async request belonged to.typeahead:asyncreceive  Fired when an async request completes. The event handler will be invoked with 3 arguments: the jQuery event object, the current query, and the name of the dataset the async request belongs to.Example usage:$('.typeahead').bind('typeahead:select', function(ev, suggestion) {console.log('Selection: ' + suggestion);});
