List not refresh after close modal popup?

Question

How can refresh a list after a close modal popup in angular?

 

I am using a list, where the edit button is present, on that button, I passed data to modal popup, update it and close the modal popup, but the list cannot be refresh.

 

The code on list component is : 

openStudentDialog(rowData: any, statusValue: any): void {
        this.rowRecordId = rowData.recordId;
        this.statusValue = statusValue;
        let dialogRef = this.dialog.open(StudentUpdateDialog, {
            width: '250px',
            data: { recordId: this.rowRecordId, statusValue: statusValue}
        });
        this.getStudentList()      //i am using this but it cannot update the list
    }

On Dialog Component code is :- 

@Component({
    selector: 'student-update-dialog',
    templateUrl: 'student-update-dialog.html',
    providers: []
})
export class StudentUpdateDialog {
    rowData: any = "";
    status: any;

    constructor(public dialogRef: MatDialogRef<StudentUpdateDialog >,
        @Inject(MAT_DIALOG_DATA) public data: any) {
        this.rowData = data;
        this.status = this.rowData.statusValue;
    }

    onNoClick(): void {
         this.dialogRef.close();
     }
    SuccessUpdate(data: any) {
    }
}
