How to find the reference to a particular view when we need to modify the controls in that view from some other view ? What is the best way to achieve this?

I am using this.createID("") to generate ID for the elements/controls in my JSviews and using view.byID()  to reference them only problem is what is

the best way to get the reference for the "view". ?

for example

View1 has table control and we need to modify(apply filter) to that table control from the View 2's controller

the way I have handled this is

this works but in a complicated scenario when there can be nested creation of new view instances it gives run time error

for example

View2 has new instance of view 1 and  View1 has new instance of View2 ( this leads to deadlock situation )

What is the best way to get reference to View1 without having to create new instance of it?
