我在这行代码下面得到错误，任何帮助或建议，我哪里可以错了
类型“ChangeEvent”上不存在属性“trim”。ts（2339）

<SearchBox
      id={'SuggestionSearchBox'}
      placeholder={'Search ' + this.props.searchTitle}
      onSearch={newValue => this.onSearch(newValue)}
      onChange={newSearchText => {
        newSearchText.trim() !== '' ? this.showSuggestionCallOut() : this.hideSuggestionCallOut();
        this.setState({ searchText: newSearchText });
      }}
    />
 private showSuggestionCallOut() {
    this.setState({ isSuggestionDisabled: true });
  }
  private hideSuggestionCallOut() {
    this.setState({ isSuggestionDisabled: false });
  }
