javascript - Why doesn't my ng-model update with Typeahead in Firefox? -

in website i'm building angularjs i've got input typeahead below use angular-typeahead. works fine in chrome, opera , safari not in firefox. problem seems in firefox model isn't updating when click typeahead suggestion.

my html looks this:

<input class="typeahead" sf-typeahead type="text" datasets="userdataset" ng-model="searchuser" > <button ng-click="sendtouser(searchuser.id)" class="btn">send</button> 

and in controller have simple function:

$scope.sendtouser = function(userid){     console.log(userid);     // more code here.. } 

in chrome, opera , safari logs int userid, in firefox logs undefined.

i made plunker here show mean (search "one", or "two").

it works in chrome, opera , safari, in firefox somehow shows undefined in console. weird thing shows undefined first time. if select second time work.

does know why doesn't work in firefox, , importantly, how can solve it? tips welcome!

this interesting dilemma.

• the typeahead sets ng-model value object once selected

• upon event (like click) runs digest cycle, framework enforces ng-model binding,assigning model value string bound input.

• firefox, unlike chrome seems enforce behavior. chrome inputs allow object value setting (just guess).

the work around change output binding:

<input class="typeahead" sf-typeahead type="text"  datasets="userdataset"  outputval="searchuser" ng-model="a" options="exampleoptions"> 

the outputval our expected value. bound random scope variable a because directive expects , uses model binding.

inside directive, changed updatescope function set selected value scope.outputval , commented out assignment model.

    function updatescope (object, suggestion, dataset) {       scope.$apply(function () {         var newviewvalue = (angular.isdefined(scope.suggestionkey)) ?             suggestion[scope.suggestionkey] : suggestion;         console.log(newviewvalue);             //ngmodel.$setviewvalue(newviewvalue);         scope.outputval = newviewvalue;       });     } 

try plunker!
