Sencha Grid Json Get data

I have this grid in Sencha

and when I get the data, it throws this data

clearly you can see that it brings me the data BR'TX'FIELDS'002 I would need the information of the parents, that is, RECEPTION AND PAYMENT SERVICE, and it was impossible for me to navigate up, someone illuminates me.

if (dataIndex.data.c5! == undefined) {

var id = Ext.id();
Ext.defer(function () {
    Ext.widget('button', {
        renderTo: id,
        width: 24,
        icon:'appresources/images/edit1.png',
        border:0,
        style:{backgroundColor: 'transparent'},
        height:24,
        listeners: {
            click: {
                fn: function (event, target) {

                    var lastCellUsed=Ext.getCmp('v_rulesConfig').lastCell;
                    var clickToShow= Ext.getCmp('v_rulesConfig').clickToOpen;
                    if(lastCellUsed!=cell){
                        clickToShow=true;
                        Ext.getCmp('v_rulesConfig').lastCell=cell;
                    }
                    if(clickToShow){
                        Ext.getCmp('panel_parametersEdition').show();
                        var ruleId = dataIndex.data["ext-53"];

                        global_ruleIdSelected = ruleId;

                        console.log(ruleId);
                        console.log('aca pase');
                        console.log(dataIndex);
                        console.log('aca pase');
                         //console.log(global_project);
                        //INVESTIGAR
                       // global_stateSelected =
                        //global_trxTypeSelected = ;

                        Ext.getCmp('v_rulesConfig').configEditParameters(ruleId);
                    }else{
                        Ext.getCmp('panel_parametersEdition').hide();
                    }
                    Ext.getCmp('v_rulesConfig').clickToOpen=!clickToShow;
                }
            }
        }
    });
}, 50);
return Ext.String.format('<div id="{0}"></div>', id);
