Mounted event doesn't get called or is updated when changes are made

[ghost]

I installed vue-class-components 8.0.0-0 for vue3 my class looks like this for ts

import { Vue } from "vue-class-component";

export default class Main extends Vue {
    public mounted() {
        console.log("Mount");
    }
}

When I update Mount, vue keeps the same old class and method, and the page also doesn'r remount
