Ionic + Angular ui-sref not generating href

我正在处理在url中传递参数的问题。据我所知，使用vm.all属性设置baseFilterurl参数是正确的，但每次我单击链接时都不会发生任何事情。我还检查了生成的html，看到的是ui sref，而不是href标记。感谢提供的任何帮助

router.js

(function () {
    'use strict';
    angular.module('app').config(routing);
    /* @ngInject */
    function routing($stateProvider, $urlRouterProvider) {
        $stateProvider
        .state('home', {
            url: '/home',
            templateUrl: 'home/home.html',
            controller: 'HomeContentController as vm'
    })
    .state('eventsList', {
        url: '/eventsList/:baseFilter',
        templateUrl: 'events-list/events-list.html',
        controller: 'EventsListController as vm'
    });
    $urlRouterProvider.otherwise('/home');
}
})();

这是我家的标签.html

   <a class="item" ui-sref="eventsList({baseFilter: vm.all})">

HomeController.js

(function () {
    'use strict';
    angular.module('app').controller('HomeContentController', HomeContentController);
/* @ngInject */
function HomeContentController($scope, $log, $ionicSideMenuDelegate, $ionicPopup, $state, rxEventsService, rxRequests, $cordovaGeolocation) {
    // Assign variable `vm` to `this` to reflect that this is a view-model.
    var vm = this;
    vm.all = "all";
        // Bindable Properties
        vm.promptUnavailable = promptUnavailable;
        // Controller Initialization
        function init() {
            console.log('init HomeContentController');
        }
        init();
        // Bindable Events
        function promptUnavailable(feature) {
            $ionicPopup.alert({
                title: 'Unavailable Feature',
                template: feature + ' is unavailable in this Alpha release'
            });
        }
    }
})();
