ngModel with a bind function not working in ng2

问题

If I do in a template of a component something like:

<input [(ngModel)]="myProperty"></input>

then it works, but if I do it with a function in my component it does not:

<input [(ngModel)]="getMyProperty()"></input>

Here is the plunkr. Tested on RC6. Why?

回答1:

Try this construction

<input [ngModel]="getMyProperty()"></input>

• use only square brackets.
