Use getSelections to get all selected records and getSelected to get the first record.

var selected = checkBoxSelectionModelObj.getSelections();

for (var i = 0; i < selected.length; i++)
{
    alert(selected[i].data.code);
}

In ExtJs docs provide method to get selected record in grid grid.getSelection(). You can refer ExtJs docs

I have create small demo to show you, how it work. Sencha fiddle example

            handler: function () {
                Ext.getCmp('testGrid').getSelectionModel().selectAll();
            }
        }, {
            text: 'Deselect All',
            handler: function () {

                    let name='';
                    selection.map(item=>{
                        name+=item.get('name')+'<br>';
                    });
                    Ext.Msg.alert('Selected Record',name);
                }else{
                    Ext.Msg.alert('Error','Please select record');
