How to render json data with @ character in its key using handlebars?

This is my json data

var data = {[email protected]: true}

In my template i am trying this way to display data but its not working

{{data.[[email protected]]}}

I even tried this way

{{data.['[email protected]']}}

and also

{{[email protected]}}

but if i had changed my json data to

var data = {john:true}

and try

{{data.[john]}}

its working and displaying the output as true

Can anyone please point me where i am making mistake ?
