Hi kenan, 
Thanks for contacting Syncfusion support. 
In custom data binding with Async pipe, we need to generate the filter query from the state passes to the service. So that the filter action will be done in the service. We have prepared a simple sample based on your requirement. Please refer to the below code example and sample link.  
export class OrderService {  
    .   .   .  
    public execute(state: DataStateChangeEventArgs): Promise<DataResult> {  
        return this.getData(state);  
    private getData(state: DataStateChangeEventArgs): Promise<DataResult> {  
        const pageQuery = `$skip=${state.skip}&$top=${state.take}`;  
        let sortQuery: string = '';  
        let filterQuery: String = '';  
        if (state.where) {  // here you can prepare the filter query  
            filterQuery = `&$filter=` + state.where.map((obj:any) => {  
                return (obj).predicates.map((predicate:any) => {  
                    return predicate.operator === 'equal' ? `${predicate.field} eq ${predicate.value}` :                     `${predicate.operator}(tolower(${predicate.field}),'${predicate.value}')`;  
                }).reverse().join(' and ');  
        this.ajax.url = `${this.BASE_URL}?${pageQuery}${sortQuery}${filterQuery}&$inlinecount=allpages&$format=json`;  
        return this.ajax.send().then((response: any) => {  
            const data: any = JSON.parse(response);  
            return {  
                count:  parseInt(getValue('d.__count', data), 10),  
                result: getValue('d.results', data)  
Please get back to us if you need any further assistance on this.

Hi kenan, 
For Custom Binding with Async pipe, the grid actions query should be generated in service by manually as per your requirement. For CheckBox or Excel filter you need to return the dataSource from the server based on some condition for the request to populate the Filter dialog with checkbox. Please refer to the below code example for more information. 
import { Injectable } from '@angular/core'; 
export class OrdersService extends Subject<DataStateChangeEventArgs> { 
  public getData(state: DataStateChangeEventArgs): Observable<DataStateChangeEventArgs> { 
      .    .   . 
     if (state.where) {  
 // here you can prepare the filter query as per your requirment 
    return this.http 
      .pipe(map((response: any) => response.json())) 
      .pipe(map((response: any) => { 
        return state.dataSource === undefined ? (<DataResult>{ 
          result: response['value'], 
          count: parseInt(response['@odata.count'], 10), 
        }) : response['value']; 
      .pipe(map((data: any) => data)); 
public dataStateChange(state: DataStateChangeEventArgs): void { 
    if ((<any>state.action).requestType === 'filterchoicerequest' ||(<any>state.action).requestType=== 'filtersearchbegin') { 
      this.service.getData(state).subscribe((e) => state.dataSource(e)); 
    } else {
