Getting a value from multiple functions

Im having an issue due to async functions on my widget

My code:

The logic is:

the main query that u get the "numero medidor, nis, tipo tipo_direccion is from a layer)

The "rotulo" is a query from another layer in the service, the result has to be in the coleccionClientes arrayList, where i ask for the id_poste and it gives me the result for the rotulo.

I have to do the same with the direccion , calle , and numero.

Since im starting to get the rotulo, my problem is i get null for the 2 rows that it has to be shown.

The result is this one in the attach.

How can i do this more efficiently? Cuz the async functions from the other layer im asking has a delay between each row.

thanks in advice! Soon i will start changing this to javascript T -T, i promise.
