Access parent component properties inside subcomponent in AEM 6.2 sightly

[divyasekar]

Hi,

I have a subcomponent(ex: child) inside an another component (ex:parent) and have cq:dialog for parent component.

I have to access parent component dialog properties inside sub component html file.

I have tried giving ${properties.title} but it did not work out. 

Could any of you tell me the solution.

Thanks

Divya
