          db.executeSql('PRAGMA foreign_keys = ON');

Execute this after creating connection and it will solve your issue ..
it worked for me.

‘PRAGMA foreign_keys=ON;’ executed and success callback invokes, but after that if I check ‘PRAGMA foreign_keys;’ it gives result ‘{foreign_keys:0}’ and its not working, accepting any integer as FK and CASCADE not working on Delete.
