This section is primarily used to add javascript and logic to a question. The first three fields allow a user to add javascript code which will be kicked off when different events occur. The three fields are javascript:-
<br/>
onFocus - will execute the code whenever a user clicks their cursor inside the question field.
<br/>
onChange - will execute whenever anything inside the question field changes, e.g. when a user types or picks a date.
<br/>
onBlur - will execute when a user clicks outside of the question field and the question is no longer selected.
