Unable to refresh the master page list on List Select Event

Hello Gurus,

I have implemented SplitApp control and I am able to populate the data on the Master Page at the time of app Initialization.

When I select one record from the master list, I am calling a backend oData service in handleListSelect event to get the data and populate it on the master page with this new data. (like, refreshing the master page list with the new information).

Once I get the data from backend, I am trying to bind the data to the context using the below code but it is not updating the list.

can anyone please take a look at the code and suggest me what I am doing wrong here.

Appreciate your help.

Thanks

Shyam
