Disable filter functionality is not working on custom filter of columns

[akashdeepg12]

In primeNg table ,

Disable filter functionality is not working on custom filter of columns and those custom filters columns have filter = "true" value.

i have created a logic for disable normal filters of columns but not working on custom filters

toggleFiltering(ColumnConfig): void {
try {
for (let j = 0; j < ColumnConfig.length; j++) {
txColumnConfig[j].filter = !txColumnConfig[j].filter;
}
}catch (e) {
console.error(e);
}
}

but it is not working on custom filters by passing flag(true/false) to filter.

please provide this solution @cagataycivici
