Ext JS form load custom object

I have a custom object currentUser, it contains bank account name, mobile number,  and I want fill the form with currentUser’s properties.

 

To load a custom object,  first define a Model, then instantiate the Model with custom object, next call loadRecord with the model object. Note that I tried Ext.form.Panel loadRecord(), it’s not working for me, Ext.form.Basic should be used here. So we need call getForm() to get Ext.form.Basic
