I got a simple question related to Outsystems Datagrid

Q: If the data grid has only one event i.e. Initialize, there must be a way to re-initialize. What could that be? Tried binding it to a variable inside of a block (with a input variable for data source) hoping it to reinitialize as the input variable changes but that too failed :(

Scenario: All the community examples talk about data updates to the grid row/column/cell etc. where the shape of the backing data structure hasn't changed

I'm dealing with a scenario where the backing data structure itself is dynamic and hence I cannot have manual column definitions and have to rely on the auto columns. However, the grid doesnt refresh the underlying data structure changes till I do a hard refresh of the page, post which it does
