events：weui-search-bar-submit，怎么监控到这个事件？methods写也不对

Start with the SearchBar component and its documentation, then inspect how the weui-search-bar-submit event is exposed. The issue names no file or test, so first determine the relevant entry point and current event guidance. Done means the supported monitoring method and the correct methods usage are clearly documented.
