How to cancel typeahead-wait-ms on key press

Question

Using an angular-ui typeahead with a wait specified

<input type="text" 
  ng-model="selected" 
  uib-typeahead="state for state in states | filter:$viewValue | limitTo:8" 
  typeahead-focus-first="false"
  typeahead-wait-ms="1000"
  class="form-control">

I would like to cancel the wait and not show typeaheads when ENTER is pressed before the wait time is reached.

Here is a plunker to play: https://plnkr.co/edit/QkYumhmcDsXexHSLALsf?p=preview

So for example, if I enter "a" and then press ENTER before 1000ms is ellapsed, the typeaheads menu should not be shown.

Thanks to oFace blur idea, I came up with this directive.

.directive('typeaheadCancelEnter', function () {
        return {
            restrict: 'A',
            link: function ($scope, elem, attrs) {

                elem.bind('keyup', function ($event) {
                    var element = $event.target;
                    var code = $event.keyCode || $event.which;
                    if (code == 13) { //Enter keycode
                      element.blur();    
                    }

                });

            }
        };
    })
