HTML

<div ng-repeat="que in questions[$state.current.name]">
                        <div ng-if="que.QuestionData._fieldType === 'text'" >
                            <text-control-dir data-que-obj="que.QuestionData" data-ng-model="answers[que.QuestionData._attributeName]"></text-control-dir>
                        {{answers[que.QuestionData._attributeName]}}
                        </div>  
                        <div ng-if="que.QuestionData._fieldType === 'select'" >
                            <select-control-dir data="que.QuestionData"></select-control-dir>
                        </div>
                        <div ng-if="que.QuestionData._fieldType === 'radio'" >
                            <radio-control-dir data="que.QuestionData"></radio-control-dir>
                        </div>
                        <div ng-if="que.QuestionData._fieldType === 'hidden' && que.QuestionData._attributeName != 'CBQ'" >
                            <hidden-control-dir data="que.QuestionData"></hidden-control-dir>
                        </div>
                    </div>

In $scope.questions have all question, I am looping in index.html. for each question i am creating a input. if $scope.answers have value for particular input I am showing in input box. this much is working. Now I want set value in answers if user changes anything in input box.

Below code is not working of directive (element.val; gives undefined)

                element.bind('change',function(){
                scope.answers[scope.name] = document.getElementById(scope.id).value;//element.value();
                console.log(scope.answers[scope.name]);
                scope.$apply();
            })

jqLite object has val method you need to call:

scope.answers[scope.name] = element.val();
