How to re-execute scripts in theme components

Where would this if I’m building a theme component? This is my code at the moment. I’m trying to re-render the footer every time there’s a route change so that the scripts would re-execute.

I’m getting weird errors.

I’m a total beginner, and I don’t know if this is the right way to go about this.

    initialize() {
      withPluginApi("0.8", api => {
        if (settings.Show_footer_on_login_required_page) {
          api.modifyClass("controller:static", {
            @on("init")
            showFooterOnStatic() {
              this.set("application.showFooter", true);
            }
        });

        api.onPageChange(() => {
          showFooterOnStatic() {
            this.set("application.showFooter", true);
          }
        });
      }
    });
