You can call grid.reconfigure(store, columns[]) method

if you want to change whole data set in grid, you can pass in another store.
if you want to change the column, you can pass in a new array of columns definition
if you want to change both store and column definition, pass in both store and columns

Look into my code, it is very small addon, and change it to your requirements.
