Describe the bug
The data inside the Chart is not updating when we change the data it is bound to.

To Reproduce
Steps to reproduce the behavior:

1. Download this project(_re-render.zip) and install the NPM packages(run: npm i)
2. Start the project(run: npm run serve)
3. Click on the "Change dataset" button

With each click of the "Change dataset" button, the "Duration" property of the first element inside the "projects" array is being changed. With this change of "Duration", the Chart should be updated.
