ShouldSecureText Works on the new characters typed but not on the old one.

[Chokaaaa]

shouldSecureText = true works only on new characters entered but it still hides for the old characters ended.

so if I am entered 2/4 numbers and got 2 of them ** (secured) and make a shouldSecureText = false the previous ** are not being affected I either need to refreshView but it deletes the all entries cause its calling a clearPin() could you please fix that? so the entered text no matter when I press it, its updates the current characters that are already exists?
