problem solved!!! :) :)

i've updated code in plunker... in case has same problem.

i had change this:

<div class="form-group">    <select id="selectvariant" ng-model="selectitem" class="form-control">       <option selected="selected" disabled="disabled">choose 1 product...</option>       <option ng-repeat="variant in variants" value="{{variant.url}}">{{variant.title}}</option>    </select> </div>

to this:

<div class="form-group">   <select id="selectvariant" ng-model="productselect" ng-options="product product.price product in variants track product.url" class="form-control">      <option selected="selected" disabled="disabled">choose 1 product...</option>   </select> </div> 

(function() {      'use strict';      var app = angular.module('testapp', []);            app.controller('testctrl', ['$scope', function($scope) {                  $scope.variants = [{        'id': 'p-12345',        'url': 'section/food/product/p-12345',        'title': 'product 1',        'price': '£21.15 - 21x15',        'description': 'lorem ipsum dolor'      }, {        'id': 'p-12366',        'url': 'section/food/product/p-12366',        'title': 'product 2',        'price': '£11.15 - 10kg',        'description': 'lorem ipsum dolor'      }, {        'id': 'p-12364',        'url': 'section/food/product/p-12364',        'title': 'product 3',        'price': '£67.15 - 60kg',        'description': 'lorem ipsum dolor'      }];        }]);      })(window, angular);
