Testing nested menu items in the action material-ui menu

Question

I want to check my menu with nested menu items. I want to be able to simulate a click on a nested menu item and see if its handler is called. I already have tests for non-nested menu items.

Here is a simple version of the test I'm trying to build:

describe("menu", () => {
 it("should click on nested nested menu items", () => {
    const testOnClickSpy = Sinon.spy(() => {});
    const component = mount(
      <MuiThemeProvider><Menu>
        <MenuItem 
          primaryText={<span id="test">test</span>} onTouchTap={testOnClickSpy}
          menuItems={ <MenuItem  primaryText={<span id="nested">nested</span>} /> }/>
        </Menu></MuiThemeProvider>
    );

    simulateEvent(component.find("#test"), "touchTap");

    expect(component.find("#test").exists()).toBe(true);  // Works fine.
    expect(testOnClickSpy.callCount).toBe(1); // Works fine.
    component.update(); // <--- Does not seem to do anything?
    expect(component.find("#nested").exists()).toBe(true); // <--- Because this item cannot be found?
  }) 
})

I use this simulateEventto simulate the touch:

require("react-tap-event-plugin")();
function simulateEvent(wrappedTarget, eventType) {
    const domNode = findDOMNode(wrappedTarget["node"]);
    Simulate[eventType](domNode);
}

I am using React 15.6.1, material-ui 0.18.6, Enzyme 2.9.1 Jest 20.0.4
