javascript - Trigger Bootstrap typeahead on paste event

Question

I've been trying to manually trigger the typeahead search on right-click paste by catching the paste event as follows but I can't seem to find a way to trigger the typeahead's 'matcher' function manually to query the entered string.

$('#search-bar').bind("paste", function(e)
{
    $(this).trigger("keydown"); // Tried keyup, input to no avail!
});

Any help would be much appreciated!

        $('#search-bar').typeahead({
            'updater' : function(item) {
              myAjaxFunction(item);
            }
        });

function myAjaxFunction (item){
$.ajax({ //DO STUFF HERE });
}

$('#search-bar').bind("paste", function(e){
    var self = $(this);
    setTimeout(function(){self.trigger("keydown");}, 0);
});

(1) 我的懒惰解决方案：调用$('#yourtypeaheadfield').trigger('keyup')“模拟”一个 keyup / keypress 事件 .. 这就是 Typeahead 与 JQuery API 挂钩的方式。

（2）“更好”的答案：明确触发 typeahead 事件$().trigger('typeahead.updater')- 但是我无法弄清楚语法，并且没有记录（至少对于 bootstrap 2.3.2 没有）。
