Using Cookies in EXTjs 3.4 to store data in a grid
===

I am new to extjs and can anyone please assist me in using the "stateEvents" property in extjs3.4.

My issue is: 

I have a form in the panel1 of a tabbbed panel. After entering data and hitting submit,the entered data will be populated in a grid. I tried storing the data in a cookie, so that on page reload it gets repopulated.It works fine for me if I use the default events given for stateEvents property.

i.e it works fine  if stateEvents:columnmove | columnresize | sortchange | 

What are the other events supported by this property?

I have seen an example like :['click', 'customerchange']

what does this 'customerchange signify?
