How to force update?

[jesusmariocalleja]

I have a grid with dynamic columns that uses sly-repeat to repeat the items. I have the attribute directive slyEvaluateOnlyWhen pointing to the array of columns, and everytime we add/remove a column, it updates properly.

The problem comes when I want to add/delete items to this grid. If I delete the initial items, it's ok, but if I add items and then I delete them, the sly-repeat just empty the object of that item, but not delete it from the grid items array.

How can I force to update the repeat?
