Greetings from Syncfusion.
Based on your requirement we have prepared sample in that we have used itemTemplate feature to change the content in the checkbox dialog. When you use the itemTemplate the template function will be called and we have changed the value based on the data. For your convenience we have attached the sample so please refer the sample for your reference.
