FormsModule has imported on app.module.ts but the problem persists.
Can't bind to 'ngModule' since it isn't a known property of 'input'.
 ("item</h1>
      <form (submit)="addItem()" #form="ngForm">
Can anyone help me?

    In your app.module.ts add the following import:
import { FormsModule, ReactiveFormsModule  } from "@angular/forms";
and add them to the imports section:
imports: [
    FormsModule,
    ReactiveFormsModule
],
Edit:
There are two possible reasons:
Missing FormsModule, hence Add this to your Module,
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
@NgModule({
    imports: [
        FormsModule      
    ]
Since you don't use the reactive forms you can remove ReactiveFormsModule from the imports.  
Check the syntax/spelling of [(ngModel)] in the input tag.
