Cant get selected rows from DataGrid after updating shiny v0.8 to v0.9

Since the recent update to the shiny framework where the row_selection_mode='multiple' argument in render.DataGrid became selection_mode = 'rows', the input._selected_rows() function also stopped working. Is there a new substitute for this?
The DataGrid documentation still states this syntax, but it doesnt work. The code is as follows:

def delete_row():
        selected_indeces = list(input.dynamic_input_selected_rows())
        if len(samples_df) > 0:
            #get all indeces in the database_df dataframe
            all_indeces = list(database_df.index)
            #remove selected indeces not in all_indeces
            selected_indeces = [index for index in selected_indeces if index in all_indeces]
            #drop the selected rows from the samples_df and database_df
            samples_df.drop(index = selected_indeces, inplace=True)
            database_df.drop(index = selected_indeces, inplace=True)
            file_paths.drop(index = selected_indeces, inplace=True)

            file_paths.reset_index(drop=True, inplace=True)
            samples_df.reset_index(drop=True, inplace=True)
            database_df.reset_index(drop=True, inplace=True)
             ui.notification_show("You have exterminated all the rows")
        def dynamic_input():
            if len(samples_df) > 0:
                return render.DataGrid(samples_df, selection_mode="rows")
                ui.markdown("No data added")

Any help would be much appreciated
