You can find an example of a callback here:

http://docs.sencha.com/ext-js/4-1/#!...ic-method-load

Check API docs and select function which you want on favourite class

E.g. store:

var myStore = new Ext.create('Ext.data.Store', {
...
listeners: {
    beforeload: function(store, operation, e){
         ...
    }
}

or on object instance:

myStore.on('beforeload', function(store, operation, e){
    //do whatever you want here
});
