angularjs - Update model outside of controller -

-

just starting out on angular, not sure how update model out of controller, or in fact if have head around do. have autocomplete field based on ion.autocomplete

html

  <span ng-controller="ionautocompletecontroller">   <label class="item item-input item-stacked-label">             <span class="input-label">item description</span>             <ion-autocomplete ng-model="model"                               item-value-key="name"                               item-view-value-key="view"                               items-method="gettestitems(query)"                                 multiple-select="false"                               placeholder="bread, milk, eggs etc .."                               items-clicked-method="itemsclicked(callback)"/>             </span>      <button class="button button-block button-royal" ng-click="scan()">scan</button>    <div class="row">  <div class="col"><b>item name</b></div>  <div class="col" ng-model="name"></div>  </div>

javascript

  var myapp = angular.module('myapp', ['ionic','ngcordova','ion-autocomplete']);    myapp.config(['$ionicconfigprovider', function($ionicconfigprovider) {   $ionicconfigprovider.tabs.position('bottom')   }]);      myapp.controller('ionautocompletecontroller', function ($scope,$http) {                 $scope.model = "";                 $scope.callbackvaluemodel = "";                 $scope.gettestitems = function (query) {                   console.log(query);                 return  $http.get('http://192.168.100.100/myapp/products/' + query).                         success(function(data, status, headers, config) {                         console.log(data);                         }).error(function(data, status, headers, config) {                         console.log("something went wrong")                             });                 };                 $scope.itemsclicked = function (callback) {                 console.log(callback);                 $scope.name=callback.item.name;                 console.log(callback);                 $scope.callbackvaluemodel = callback;                 }             });

what happening here autoselect grabbing data rest server , results place in autocomplete. when item selected callback returned in json array. want callback place in ng-model="name" out of controller. or assume why not updating.

your ng-model="name" binds $scope.name in controller. when data returned rest call, set $scope.name = data.
