thepackages/presets/src/fragments/doc-title/doc-title.ts as follow,

  // eslint-disable-next-line @typescript-eslint/member-ordering
  private handleChangeTitle() {
    (this.doc.root as RootBlockModel)?.title.replace(
      0,
      this._rootModel.title.length,
      Math.random() + ''
    );
  }

  override render() {
    const isEmpty = !this._rootModel.title.length && !this._isComposing;

    return html`
      <div
        class="doc-title-container ${isEmpty
        ? 'doc-title-container-empty'
        : ''}"
        data-block-is-title="true"
      >
        <rich-text
          .yText=${this._rootModel.title.yText}
          .undoManager=${this.doc.history}
          .verticalScrollContainerGetter=${() => this._viewport}
          .readonly=${this.doc.readonly}
          .enableFormat=${false}
        ></rich-text>
        <div @click=${this.handleChangeTitle}>点击我，更新title内容</div>
      </div>
    `;
  }

the key class is Text in packages/framework/store/src/reactive/text.ts , which has alot of func to change it
