Mat-darepicker не берет дату из ngModel?

<mat-form-field class="full-width-field">
	<input matInput [(ngModel)]="form.date_to" [matDatepicker]="picker" placeholder="Дата задачи">
	<mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
	<mat-datepicker #picker></mat-datepicker>
</mat-form-field>

form = {
		id: null,
		user_id: null,
		comment: null,
		type: null,
		date_to: null,
		task_object: null,
	};
initFormValues() {
		Object.assign(this.form, this.data['model']);
		this.form.date_to = moment(this.data['model']['date_to']); //делал и так
	}

let dialogRef = this.dialog.open(TasksEditModalComponent, {
				width: '650px',
				minHeight: '250px',
				data:
					{
						model: task,
						users: users,
					}
			});
