Add fix #606: Overflow Issue Resolved

[Gaurav-Kushwaha-1225]

Description

This overflow issue was due to NumberPicker widget, when the min and value arguments of this widget were 1 or greater, then it shows this overflow error.

Proposed Changes

How I resolved?

• I changed the min and default value of numMathsQuestions as 0 and 0.obs, respectively.
• Then, in Save button of dialog, it will check for condition, that for setting controller.isMathsEnabled.value to true the number of questions should be greater than 0.
• Else, it will remain false by default and Maths Challenge will not be enabled until you select number questions to be greater than 0.
