Please check this

In controller file add the following:

 $scope.onSelect = function ($item, $model, $label) {
$scope.$item = $item;
$scope.$model = $model;
$scope.$label = $label;

};

In view add the following:

<input type="text"
    ng-model="selected"
    typeahead="state for state in states | filter:$viewValue"
    typeahead-editable="false"
    typeahead-on-select="onSelect($item, $model, $label)"/>
