怎么将拼接的字符串element组件通过“v-html“渲染到页面

如上图所示，没那么多废话，直接上代码

html中

<div id="app">
  	<div :html="tempHtml"></div>
</div>

vue中

new Vue({
     el: '#app',
     data() {
         return {
             tempHtml: ''
         }
     },
     created() {
         this.getHtml()
     },
     mounted() {
         window.clickFun = this.clickFun;
     },
     methods: {
         getHtml() {
             let template = "<el-button type='primary' size='mini' @click='clickFun()'>查询</el-button>"
             this.tempHtml = template;
         },
         clickFun() {
             console.log(121212);
         }
     },
     render(h) {
         const com = Vue.extend({
             template: eval('`' + this.tempHtml + '`')
         });
         return h(com, {});
     }
 })
