Grid filter list options

Hi :) ,

I'm trying to change a grid filter list options, here is my code :

Code:

Ext.getCmp('Plan').getView().getHeaderCt().child('#METIER').initialConfig.filter.options = store.collect('METIER');

This seems to work, the object is well updated.

But the filter menu is not changing.

What do I have to do more to apply the new list options ?

Thanks in advance,

Charlotte.
