Dynamic value in QuickFilter

Hello. I need to create a QuickFilter on a Freedom UI Page whose value will change dynamically. I found a post https://customerfx.com/article/using-custom-attributes-on-a-creatio-fre… so I try to use the attribute but it does not work. Could you help me please?

{
    "filterType": 1,
    "comparisonType": 3,
    "isEnabled": true,
    "trimDateTimeParameterToDate": false,
    "leftExpression": {
        "expressionType": 0,
        "columnPath": "MyColumn"
    },
    "isAggregative": false,
    "dataValueType": 1,
    "rightExpression": {
        "expressionType": 2,
        "parameter": {
            "dataValueType": 1,
            "value": "$MyAttribute"
        }
    }
}
