Pull Refresh event on Sencha Architect

Question

I have a list of items connected to a web server.

When the user pulls down the list it refreshes all items on the list.

I am using Sencha Architect, how can I do this? I'm using an Ext.plugin.pullrefresher , but I can't find the way to bind the action of pulling with the function that updates the list.

plugins: [
                    {
                        pluginId: 'refArrivos',
                        type: 'pullrefresh'
                    }
                ]

How to add some code related to the event? Thanks
