Coach>Reports>Quiz score - Incorrect number of attempts

[pcenov]

Observed behavior

I see an incorrect number of attempts at 'Coach>Reports>Quiz score' whenever there's a numeric value input as the answer to a quiz question. For example if the answer is '12' I will see one failed attempt for the first entered digit '1' and one successful attempt for '12'

Steps to reproduce the issue

1. Install Kolibri 0.15.2
2. Import Khan Academy's (English - US curriculum) > Math by grade > 3rd grade > Represent and interpret data > Picture graphs
3. Create a quiz for 'Read picture graphs (multi-step problems)'
4. Complete the quiz and as a Coach go to Coach>Reports>Quiz score

Expected result

Correctly displayed number of attempts.

I believe we removed the debounce on the input because it was too long, but seems like we may need something in the 250ms range?
