DataList control in POS unable to select the Items

[LavanyaNiki]

We have created a new custom form with DataList Control to display a list of information. We select a few things from the Grid, for example, vouchers 1–3 and add them to our transaction.

Then I can go back and check the form to see if I've previously associated the sale. In this case, my previously selected things are unchecked.

How do I keep the selected items in the datalist?

Followed this documentation: https://learn.microsoft.com/en-us/dynamics365/commerce/dev-itpro/pos-extension/controls-pos-extension

and added additional line as below in the OnReady function but no luck.
this.dataList.selectItems(this.viewModel.voucherNumbers);

Please let us know how to handle this issue?
