Modify Emmet HTML Replacement code Follow

I'm wondering if there is a way to modify the Emmet replacement code templates.  If I type `.row` and expand it out I get this: `<div className='row'></div>`.  I am using JSX in React so what I really want is `<div className={'row'}></div>` with those curly brackets added in.  Anyone know how I can modify those templates?

Thanks

Mike
