为什么我的click方法，不能改变content内容，点击没有效果
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Vue 学习</title>
<script type="text/javascript" src="vue.js"></script>
</head>
<body>
<div id="root">
<h1 v-on:click="handleClick">{{content}}</h1>
</div>
<script type="text/javascript">
new Vue({
el: "#root",
data: {
content: "Hola"
},
methods: {
handleClick: () => {
this.content = "Suremotoo";
}
}
});
</script>
</body>
</html>
