IOS with VoiceOver does not focus on Canvas and unable to draw on canvas while VoiceOver is on

Hi,
I’m using Angular2-SignaturePad in ionic app. It works fine with IOS but, as soon as VoiceOver is enabled then the signature pad stops getting focused and the user is unable to draw on it as well. On Android, it works fine while androids talkback is on.
