I have a listbox in a MVVM form that uses the checkmark and multiple attributes, like:

<listbox model="@load(vm.children) @save(vm.children,before='save')" checkmark="true" multiple="true" selectedItems="@bind(vm.selectedChildren)" width="150px">

I cant' work out how to set the initial 'checked state of the items in the list box.

Any suggestions?

I've tried using model.addToSelection and it doesn't work.
