angular.js:14525 typeerror: cannot read property 'value' of null

my recaptcha code 

<div vc-recaptcha key="my key here" ng-model="letter.myrecaptcharesponse" on-create="setrecaptchaid(widgetid)"> </div>

my controller code 

$scope.setrecaptchaid = function(widgetid) {     $scope.recaptchaid = widgetid;     return; }; $scope.letter.mresponse = vcrecaptchaservice.getresponse($scope.recaptchaid);
