BUG-Data is not updated in the data section of Data Node viewer

[FlorianJacta]

Description
The Data in the Data Node section of the Data Node viewer is not updated after executing a scenario. The only way to show the update is to refresh the page.

How to reproduce
Run this code. The initial value is 'District 1'. This is what can be seen inside both data node viewers. Change the district to 'District 2' and submit the scenario. What is inside the Data Node Viewer hasn't changed. It is still District 1 even after completion. Now, refresh the page. It is now District 2, as it should be.

    scenario.first_district_name.write(district_one)

    tp.Gui(page=md).run(
        title="From Taipy Quine Quest-007", port=2445, host='0.0.0.0')

Expected behavior

The Data should be updated.

Runtime environment
Taipy: 3.1.0

Acceptance Criteria

• Ensure new code is unit tested, and check code coverage is at least 90%
• Create related issue in taipy-doc for documentation and Release Notes if relevant
