Redirect Url on Client Side

@Teodor @Patrick

I have been trying to get the server connect to go another page if the condition is not met. I am having trouble with the event.
When I submit the form: It works fine in server side but it does not go the page savecard.php on the client side.
I tried dmx-on:done="ChargeCamp.StripeCustomer.listPaymentMethods.data.keys()? browser1.goto('/Lead/savecard.php') : false but no good outcome.

Any help will be very appreciated.Thank you
