Client Script

This is the controller already linked to the widget. Consider every widget to be an Angular directive – you define the controller for that directive here. This is where you handle all the client-side logic and template binding for your widget.

function() {    
    var c = this;
    c.update = function() {
        c.data.price = false;
        c.server.get({symbol: c.data.symbol}).then(function(r) {            
            c.data.price = r.data.price;            
        });
    }
}
