The track would be correct but unfortunately it isn't idiom."To be on a roll "= be on the scent isn't it ?

Hi Kati,
"To be on a roll" means to be experiencing 'sustained fortune or success in some area.'
"To be on track" (without an article {a or the}) means to be 'achieving or doing what is necessary or expected.'
"To be on the track of" OR "to track down" means to be 'pursuing or on the scent of something/someone.'
