How to add/remove fields from store Ext.net 2.2

[rishu]

I was updating the store fields dynamically with the code mentioned in below snippet for earlier versions of Ext.net but now i am not getting alternative approach to solve my issue.

var fields="field1~field2~field3";

function reconfigFields(store, fields) {
            var fieldArr = fields.split('~');
            if (fieldArr.length == 1 && fieldArr[0] == '') { return; }
            var i;
            while (store.fields.getCount() > 0) {
                store.fields.removeKey(store.fields.getKey(store.fields.itemAt(0)));
                store.fields.removeAt(0);
            }
            for (i = 0; i < fieldArr.length; i++) {
                store.fields.add(fieldArr[i], new Ext.data.Field({
                    name: fieldArr[i]
                }));
            }
        }

Now, i am able to remove all fields by the function store.removeFields(); but to add new fields i am not getting any method. Please help me to solve my issue with Ext.Net upgrade.

Store has 'addField' method

I need a way to do it through js side and got the solution by using store.model.setFields(fieldsArray);
