Problem with Extjs 4.1 autoload

Hello All,

I am using Extjs 4.1
I have attached a dynamic editable grid (please refer dy_grid.jpg). The status column is a combo box type editor.
Please look into issues.jpg. My main requiremnt is that it should be called the moment the grid loaded.

But, if I am clicking on any of the cell of status column, then only the corresponding url (please refer issues.jpg) getting called to populate data into the combo box.
I have made autoload as true. But looks like it is not working. Please refer another image combo_store.jpg



Thanks,
Soban

So when the combobox is first created, the store doesn't load?
