save&close is not triggered when changing datasource or id

[AlexanderPico]

steps to reproduce:

1. click datanode and open editor (or vice versa)
2. change datasource and/or id

expected:

• save&close tab/button is active

observed:

• not active; can only close without saving

Now it changes if no activity for 700ms. OK?

Still not triggered when DEL is clicked, even just once, e.g., when changing "ABC12" to "ABC1". Maybe we need a slightly different event listener...

It works for me.

Tested on Chrome with this pathway: http://pvjs.wikipathways.org/index.php/Pathway:WP4

1. Open editor
2. Select "ADP"
3. Delete the last character from the identifier so "HMDB01341" becomes "HMDB0134"
4. Waited <2 sec.

The Close button turned into the green Save&Close button

Works for me on Chrome, but there is a delay (~2seconds) before the button changes state. Also, an immediate reversal of the change without closing QuickEdit (i.e. changing the data source back to what it was originally, or adding the last number of the identifier that was just deleted), doesn't trigger the button state to go back to Close. In contrast, changes to the display name don't have the same delay in button state change, and reversal works as expected.
