angular2 pipe Template parse error

Question

i am trying to implement a simple search using pipes. I am really new to the concepts of pipe and angular2, so i need your help

here is my html:

<input  type="textarea"  placeholder="branch" [(ngModel)]="search.branch" name="branch">
 <tr *ngFor="let loan of loans | loanfilter:search.branch ">
            <td><input type="checkbox"></td>
            <td>{{loan.loanId}}</td>
            <td>{{loan.custName}}</td>
            <td>{{loan.vehicleNum}}</td>
            <td>{{loan.TC}}</td>
            <td>{{loan.RE}}</td>
        </tr>

loan.component.ts:

import { Component } from '@angular/core';
import { LoanService } from '../../services/loans.service';
import { Loan } from '../../../loan';
import { Injectable, Pipe, PipeTransform } from '@angular/core';
import { LoanFilterPipe } from '../../pipes/loan.pipe';

@Component({
    moduleId: module.id,
    selector: 'loans',
    templateUrl: './loans.component.html',
    providers: [LoanService],
    declarations: [LoanFilterPipe]  //getting error on this line: Object literal may only specify known properties, and 'declarations' does not exist in type 'Component'.
})

export class LoansComponent{

    loans : Loan[];
    custName: any;

    constructor(private loanService: LoanService){
        this.getloans();
    };

    getloans(){
        this.loanService.getLoan()
            .subscribe(loans => {
                this.loans = loans;
                console.log(loans);
            });

    }
};

the errors i am getting are:

Uncaught (in promise): Error: Template parse errors: Can't bind to 'ngModel' since it isn't a known property of 'input'

loan.pipe.ts:

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
    name: 'loanfilter'
})

export class LoanFilterPipe implements PipeTransform{
    transform(loans: any[], args: any): any{
        return loans.filter(item => item.title.indexOf(args[0].title) !== -1);
    }
}

I have also used a module.ts file to declare the pipe and all other components:

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpModule } from '@angular/http';

import { LoansComponent } from './components/loans/loans.component';
import { LoanFilterPipe } from './pipes/loan.pipe';
import { AppComponent }  from './app.component';

@NgModule({
  imports:      [ BrowserModule, HttpModule ],
  declarations: [ AppComponent, LoansComponent, LoanFilterPipe ],
  bootstrap:    [ AppComponent ],
  exports:      [LoanFilterPipe]
})

export class AppModule { }

Answer 1

Import FormsModule in you app module.

import { NgModule }      from '@angular/core';
import { FormsModule }   from '@angular/forms';
import { BrowserModule } from '@angular/platform-browser';
import { HttpModule } from '@angular/http';

import { LoansComponent } from './components/loans/loans.component';
import { LoanFilterPipe } from './pipes/loan.pipe';
import { AppComponent }  from './app.component';

@NgModule({
  imports:      [ BrowserModule, HttpModule, FormsModule ],
  declarations: [ AppComponent, LoansComponent, LoanFilterPipe ],
  bootstrap:    [ AppComponent ],
  exports:      [LoanFilterPipe]
})

export class AppModule { }

Answer 2

you are missing FormsModule in your code

because according to angular FormsModule is must to add while bootstraping if you are using ngModel because as of now ngModel is a part of FormModule

Answer 3

As the other answers suggest you have to import FormsModule

Also you have set search.branch as ngModel which is not declared in the component typescript file.

And also you dont have to give declarations array in component decorator. Remove declarations: [LoanFilterPipe] from the @Component.

It is given in the NgModule.You dont have to put it in export unless you are going to use in another module.
