angular2 rc.5 custom input, No value accessor for form control with unspecified name

I have simple custom input component like this,

import {Component, Provider, forwardRef} from "@angular/core";
import {ControlValueAccessor, NG_VALUE_ACCESSOR} from "@angular/forms";


const noop = () => {};


const CUSTOM_INPUT_CONTROL_VALUE_ACCESSOR: any = {
provide: NG_VALUE_ACCESSOR,
useExisting: forwardRef(() => CustomInputComponent),
multi: true
};


@Component({
selector: 'custom-input',
template: `


<input class="form-control"
[(ngModel)]="value" name="somename"
(blur)="onTouched()">


`,
providers: [CUSTOM_INPUT_CONTROL_VALUE_ACCESSOR]
})
export class CustomInputComponent implements ControlValueAccessor{


//The internal data model
private _value: any = '';


//Placeholders for the callbacks
private _onTouchedCallback: () => void = noop;


private _onChangeCallback: (_:any) => void = noop;


//get accessor
get value(): any { return this._value; };


//set accessor including call the onchange callback
set value(v: any) {
if (v !== this._value) {
this._value = v;
this._onChangeCallback(v);
}
}


//Set touched on blur
onTouched(){
this._onTouchedCallback();
}


//From ControlValueAccessor interface
writeValue(value: any) {
this._value = value;
}


//From ControlValueAccessor interface
registerOnChange(fn: any) {
this._onChangeCallback = fn;
}


//From ControlValueAccessor interface
registerOnTouched(fn: any) {
this._onTouchedCallback = fn;
}


}

and I have app module like this,

/**
* Created by amare on 8/15/16.
*/
import { NgModule }                     from '@angular/core';
import { BrowserModule }                from '@angular/platform-browser';
import { ReactiveFormsModule, FormsModule }          from '@angular/forms';
import { AppComponent }                 from './app/app.component';
import {CustomInputComponent} from "./app/shared/custom.input.component";
import {RouterModule} from "@angular/router";
@NgModule({
imports: [ BrowserModule, ReactiveFormsModule, FormsModule, RouterModule ],
declarations: [ AppComponent, CustomInputComponent],
bootstrap: [ AppComponent ]
})
export class AppModule {
}

and main

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule }              from './app.module';


platformBrowserDynamic().bootstrapModule(AppModule);

and I have used my custom input in one of my components as shown below, but am getting 'No value accessor for form control with unspecified name attribute'.

<custom-input name="firstName" [(ngModel)]="firstName"></custom-input>

and the app.component looks like this

import { Component } from '@angular/core';


@Component({
moduleId: module.id,
selector: 'app-root',
templateUrl: 'app.component.html',
styleUrls: ['app.component.css']
})
export class AppComponent {
title = 'app works!';


firstName: string;
}
