Dynamically font size changing in tableview

I want to dynamically change fontsize inside my tableview data, i know how to do it using labels - label.text = 'new words'; but i have no idea how can i change it inside tableview with a lot of data. Is there any solution to that?

var table = Ti.UI.createTableView({
    separatorColor: "#fff",
    data: [{
        title : Az
        module : 'Az',
        font:{fontSize: fonts},
    },
     {
        title : 'Kat',
        module : 'Kat',
        font:{fontSize: fonts}
    }]
});
