Ionic2 - Sqlite - Transaction not working

Hy guys,

I’m using sqlite in my ionic2 project, and it works just fine except the transaction part.
So when i call this.db.query(…), it works just greate, i can create tables read from them and update the data, but i wan to use a transaction at one part, and when i call this.db.transaction(…) i get this error:

"TypeError: Object # has no method ‘transaction’ "

Does anyone know why is this?
Thanks in advance for any help.
