Question

我有以下代码：

<template is="dom-repeat" items="{{todos}}" sort="sortComparator">
                <div class="row">
                        <paper-icon-button icon="arrow-forward"></paper-icon-button>
                    <span>{{item.name}}</span>
                    <span class="btn-set">
                        <paper-icon-button icon="delete" on-tap="deleteTodo">delete</paper-icon-button>
                        <paper-icon-button icon="star" on-tap="toggleFavorite">star</paper-icon-button>
                    <span>
                </div>                              
            </template>

如果icon="star"为真，我想向item.isFav添加黄色。但我无法找到办法。任何建议，如何做。
