Raddata will not work on web



i tried in all possible way . this code is very simple and this is not working…


May I know where you have defined person in your view model?


sorry sir, i dont know how to define, and all examples i came across is through angular and type script and their they define person using constructor, which i tried here but stuck in errors. so i removed {{ }} . i just want two text fields , a blank text field where i can validate username and password. but i stuck in first step and cannot go further.
