Iframe updated content input not selected right?

Hi

Im wondering if anyone else is experienced this problem.

Im having a merchant app where my payment method comes from an external iframe.

On my profile i press payment method.

I get an iframe showing my current method.

In that iframe there is a button -> change method.

Pressing change method change the content of the iframe(normal link behavior) and a page with input fields are shown and the first input field is selected and the keyboard is shown (numberpad).

But as i press the numbers on the pad nothing is added to the input field. Changing field and it start working.

Any help appreciated. As it also makes the app crash if i try to type and then press the field (that all users will try…)
