plus.gallery.pick回调方法不执行（表单中选择图片）

<form class="mui-input-group">  
    <div class="mui-input-row" id="ShouJiHaoDiv">  
        <label>手机号</label>  
        <input id='account' type="number" class="mui-input" placeholder="请输入手机号">  
        <button type="button" id="YanZhengMa" class="mui-btn mui-btn-primary">获取验证码</button>  
    </div>  
    <div class="mui-input-row">  
        <label>密码</label>  
        <input id='password' type="password" class="mui-input-clear mui-input" placeholder="请输入密码">  
    </div>  
    <div class="mui-input-row">  
        <label>确认</label>  
        <input id='password_confirm' type="password" class="mui-input-clear mui-input" placeholder="请再次输入密码">  
    </div>  
    <div class="mui-input-row">  
        <label>验证码</label>  
        <input id='YanZhengMaTxt' type="text" class="mui-input-clear mui-input" placeholder="请输入验证码">  
    </div>  
    <button id="test" class="mui-btn">test</button>  
</form>  

document.getElementById("test").addEventListener("tap", function() {  
    console.log("开始选择图片");  
    plus.gallery.pick(function(path) {  
        console.log(path);  
    }, function(e) {  
        console.log("取消选择图片");  
    }, {  
        filter: "image"  
    });  
});

代码是这样的，当我点击按钮时，执行图片选择，回调显示图片地址（因为要上传），在实际操作过程中，开始选择图片这里执行了，然后选择回调和没选择回调都没有执行，求帮助
