angular - How to use expression for (click) event -

in angular2 have multiple buttons , on click set value. possible use expression in click event ie., instead of calling function can set value directly?

<button (click)="setvalue(1)">1</button>  <button (click)="setvalue(1)">2</button> <button (click)="setvalue(1)">3</button> 

to thing like

<button (click)="{{value=1}}">1</button>  <button (click)="{{value=1}}">2</button> <button (click)="{{value=1}}">3</button> 

you can use expressions don't use {{}}

<button (click)="value=1">1</button>  

angular evaluates value part when attribute name wrapped in [], () (or both [()] or when value contains {{}}. don't use [] , () {{}}.

{{}} stringifies result. if want bind non-string values properties don't use {{}} @ all.
