Removed callback functions for fixing ZEN-14350

Some changes that fix disabling of the button
Actually we can't add the same service(invalid in our case) to the server, there is another script that not allow us to do that and we get flare message that talks about it. We do the same when we use previous approach(invocation this.markInvalid) but in this way I do it directly. Merely invocation callback function makes time of waiting response too long and the button changes it state. We used to have this approach at 4.2.6 version, but when someone made validation, rewrite this part of code. I tested different approaches on my AWS and this works. So, if you not agree with that I will be able to find another solution I think.
