off string binding

how come whenever i bind my yoyo when it lands on the string it wil just siide and fall off?
i tried binding for a long time but it still wont go up?Any advice or help?

and also does a responsive or unresponsive affecth off string playing?

What yo-yo are you using?

Try doing a double bind. Also, if your gap is wide, its gonna make it harder to get it back.
