javascript - AngularJS dynamically changes $resource -

i making first mean app , have problem angular. in app loading resource places in controller wrote this:

$scope.place = $scope.places.$promise.then(function (collection) {     collection.foreach(function (place) {         if (place._id === $routeparams.id) {             $scope.place = place;             $rootscope.map.address = place.address;             map.initmap(place.mapcoords);         }     }) }); 

it loads perfect place on page am. , on page have this:

.row     .col-lg-4         .form-group             label Описание             textarea.form-control(rows='5', ng-model="place.description", required)     .col-lg-4         .form-group             label Сайт             input.form-control(ng-model="place.website")     .col-lg-4         .form-group             label Адрес             input.form-control(ng-model="place.address", ng-change="getaddress(place.addres)", required)     .col-lg-4         .form-group             label Снимка             img(ng-src="{{ img_src || '/img/uploads/' + place._id + '.jpg' }}", height="100px", width="100px")             i.fa.fa-spinner.fa-spin.fa-4x(ng-show="img_load")             input.form-control(type="file", file-model="place.pic") #map  .btn.btn-primary.btn-lg.pull-right(ng-click="update(place)", ng-disabled="editplaceform.$invalid") Обнови .btn.btn-danger.btn-lg.pull-right(ng-click="delete(place._id)") Премахни 

the problem when change input value saves in resource without calling function this. maybe because resource cached? solutions? in advance!
