Bind a cuco from component A to component B

Hi guys, I´m having trouble binding a value node in component "A", to a value node in a custom controller in component "B", this is my relationships and value flow.

1.- view MODEL node of component "A" in GET_XXXX method set the property of view VALUE node of component "A".

(Set is ok)

2.- view VALUE node of component "A" -> cuco value node of component "A".

(Added by wizard / CREATE_ cuco value node of component "A".

(Added by wizard, component "A" using the Component/Cuco/Node).

this second step is where I´m not sure if something is missing, extra code needed, do everyone has any tip or documentation about bind a cuco from other component !? or maybe I get complicated about my solution.

thanks
