Can I dynamically add property to the model by changing the property of controls with data binding?

Hi all,

I try to bind model to the control —item. And the property 'selected' bind to model which is undefined by default. Whether the property will be added if I select this item? I try it and found it can't be created. So the way is to catch the select event and call setProperty of model to add it? Thanks for any suggestion.

    Hi Mengchi,

    You mean something like this? Plunker

    Checked is a property added in the model. And once you check the combobox placed in each item, you see the value gets changed to true / false.
