Hi Csaba,

The idea of the formatObject.template is to set the template once and update it afterwards with the values from the data source coming to the template function. In the provided code, the template is always set to an empty string i.e there is no reuse in the current situation. I would suggest you check this sample: https://www.htmlelements.com/react/demos/grid/column-dynamic-template-with-components/
