Grid Column Renderer not called

I have an issue with a rally grid column render not getting called when using the filtering plugin.

When first entering the page it works fine, even the filtering. But if I do a page refresh (browser F5 or go to another page and back) the renderer function is not called.

Is this a bug or feature?

Can I force the renderer function to be called somehow, e.g., in the store load event?

Here's a small example showing the behavior;

Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function () {

    Ext.create('Rally.data.wsapi.TreeStoreBuilder').build({
        models: ['PortfolioItem/Initiative'],
        enableHierarchy: true
    }).then({
        success: this._onStoreBuilt,
        scope: this
    });
},


_onStoreBuilt: function (store) {
    var modelNames = ['PortfolioItem/Initiative'];
    var context = this.getContext();

    this.add({
        xtype: 'rallygridboard',
        context: context,
        modelNames: modelNames,
        toggleState: 'grid',
        plugins: [
            'rallygridboardaddnew',
            {
                ptype: 'rallygridboardfieldpicker',
                headerPosition: 'left',
                modelNames: modelNames,
                stateful: true,
                stateId: context.getScopedStateId('grid-fields')
            },
            {
                ptype: 'rallygridboardinlinefiltercontrol',
                inlineFilterButtonConfig: {
                    stateful: true,
                    stateId: context.getScopedStateId('grid-filters'),
                    modelNames: modelNames,
                    inlineFilterPanelConfig: {
                        quickFilterPanelConfig: {
                            defaultFields: [
                                'ArtifactSearch',
                                'State'
                            ]
                        }
                    }
                }
            }
        ],
        gridConfig: {
            store: store,
            columnCfgs: [
                'Name',
                'State',
                {
                    text: 'Refined',
                    dataIndex: 'RefinedEstimate',
                    renderer: function (value) {
                        console.log("RefinedEstimate:renderer");
                        return value + " EUR";
                    }
                }
            ]
        },
        height: this.getHeight()
    });
}

});

I have gotten a confirmation that this is a bug.

Might not be prioritized due to focus on new framework using React.
