Extjs 4 grid: Add a checkbox column without attaching to a datafield

I need to have a column in my Extjs grid with a checkbox which doesn't have a data field assigned to it. I have tried checkColumn plugin but it only works when I assign a data field to it.

What I mean is that it works for the following code:

{header: 'Business Call?',dataIndex: 'business', width: 55, xtype: 'checkcolumn'}

But for this code, it only displays a checkbox, but it's not clickable:

{header: 'Set Business Call', width: 55, xtype: 'checkcolumn'}

What I want to happen is, when the user ticks the checkbox, I need to do some operation on the respective database row. Is this possible with Extjs?

What are you planning on doing with the clickable checkbox? If it's simply the act of clicking that you're trying to intercept, what is harmed by specifying a dataIndex?

Remember that you should add the picture of checkbox to ur images from extjs-->resources-->images-->default-->grid

{
 xtype: 'checkcolumn',
 header: 'Capital City',
 dataIndex: 'CapitalCity',
 editor: {
          xtype: 'checkbox',
          cls: 'x-grid-checkheader-editor'
          }
}
