DataTables .draw() not firing properly

I was having a very similar problem. This worked for me:

table.rows().invalidate().draw()

You should be able to use table.destroy(); immediately before table.draw();. It's likely that you're "filtering" somehow before you do the table draw, which is causing this problem. table.destroy(); will take out any filtering and then you can draw from scratch.
