I just made a correction.

In fact when inserting data, I increased the pageSize variable by 1 but the problem is that this variable is not reset during the next initServer.
So I created a backUp system in order to reset this pageSize variable.
Additionally, now in the insertRow the this.data variable contains the options data, why is this important? This is due to another bug which consists of when we add a row at index 0 and we want to modify the row at index 1 by clicking on it for example and the event gives us the 'index 1 but actually gives us the row with index 2 because he did not put our new row in this.data because we are in server mode.

Here is an example of a use case where we would like to retrieve the row clicked following the insertion of a row :

Here is an example of the final usage, but I don't understand.
The libraries section does not take my latest commits and therefore it does not work.

I'm going to work on a cleaner system closer to that of client mode. And of course the debugs of the bugs that I cited too
