1. when we enter characters in the Search Text box on change event will call list api 2. Each time will refresh Helper after call rest Issues: API will return 10 records for each character entered, so when we type 3 characters in Search Text, all 30 records are binding in list view, but we need only the last API 10 records to be displayed Will tried to delete previous list before each api call. Above issue will face only when we try to enter character faster.
