extjs - Sencha Touch : dynamically update grouper function -

i have sencha touch 2.3 app has list grouped-

grouped: true,

the grouper function defined in store -

grouper: { groupfn: function(record) { homecoming record.get('name'); } }

all works fine. now, during runtime, want update grouper function, eg: grouping other record attribute location

how do dynamically?

i plan update grouper function when user taps button (eg: user wants see list of records grouped location)

how accomplish this?

i believe can utilize setgrouper method provided store class : http://docs.sencha.com/touch/2.3.2/#!/api/ext.data.store-method-setgrouper

you need specify gouper 1 time again :

yourstore.setgrouper({ groupfn : function(record) { homecoming record.get('location'); } });

you may have refresh list manually, don't think there event fired change, , caught list repaint.
