DDJ-WeGo2+Traktor+ipad

Why can I not use my DDJ-WeGo2 to control Traktor on my iPad?

That is why I bought it. As the man said 'it comes with an iPad connector'.

Unfortunately the connector was the new one and my iPad has the old one. So I buy a new iPad with the new connector. I plug it in and nothing. I search and find nothing. I live a long long way from the nearest shop to buy such things and I am now back again without the controller doing what I wanted it to do.

I just want to carry the WeGO and my iPad to play music.

Can anyone help please?
