[IMPORTANT BUG] All ajax Buttons are broken after update.

The Ajax buttons are broken after updating the latest scriptcase version, they are not working properly.

Steps to reproduce the bug:

1.- Create a new Ajax button.
2.- Put some code in it (For example "echo “hello”; ")
3.- Generate and Run application.
4.- Clic on the button one time. (The code will run ok.)
5.- Clic again. (The button wont do anything after the first clic).
6.- Clic again and again and again and get really mad.

I hope you guys fix this bug really soon. Thanks.
