It’s a simple. You need use actioncolumn:

{
     text: 'Is active',
     xtype: 'actioncolumn',
     align: 'center',
     dataIndex: 'is_active',
     width: 70,
     renderer: function (value, metaData, record, row, col, store, gridView) {
         if (value == null || value == true) {
             return '<img action="disable" src="/path/to/image.png" title="Some title" class="grid-icon" />';
         } else {
             return '<img action="enable" src="/path/to/image.png" alt="Is Default" title="Some title" class="grid-icon" />';
         }
     }
}

And in youre controller:

    init:function() {
        this.control({

            ...

            'panel[itemId=mygrid] actioncolumn': {
                click: function(grid, cell, row, col, e) {
                    var record = grid.getStore().getAt(row),
                        action = e.getTarget('.grid-icon', 3, true).getAttribute('action'),
                        message;

                    if(action == 'enable') {
                        message = 'Clicked "enable" for '+record.get('name');
                    }else if(action == 'disable') {
                        message = 'Clicked "disable" for '+record.get('name');
                    }
                    alert(message);
                }
            }

            ...

        });

        ...
    }
