ARIS Report update table with event

Dear all,

I have a report that shows some data in a dialog in a Table. Now I also have a button in the dialog to replace the data in that table:

var data = [];
data.push([true, "test", "test", "test", "test"]);
this.dialog.getPage(0).getDialogElement("DetailsTable1").setItems(data);

After running the code I expect the table to be updated, but it never gets updated.

I have another simple test button that does the following:

this.dialog.getPage(0).getDialogElement("DetailsTable1").addRow();

This adds a simple row and does work.

What do I need to do update the table with new data after a button click?
