单击按钮后在Ionic上切换项目

Question

我试图弄清楚为什么用Angular切换Ionic并不起作用。我认为离子导航按钮和离子含量的范围是相互矛盾的。

<ion-view view-title="Movimentação">
     <ion-nav-buttons side="right">
        <button class="button button-icon" id="header-filter" ng-click="showFilters = showFilters ? false : true">
            <i class="icon ion-search"></i>
        </button>
    </ion-nav-buttons>

    <ion-content>
        <ul class="list" ng-show="showFilters">
            <label class="item item-input item-select">
                <div class="input-label">
                    CRAAI
                </div>
                <select>
                    <option ng-repeat="item in craai"> {{ item.regiao }} </option>
                </select>
            </label>
        </ul>
    </ion-content>
</ion-view>

任何人都可以帮忙吗？
