angular - Error with DatePicker -


i have application in angular 2 typescript.

now, task <input /> tag type="date", , add tag <input type="date"> [value].

my value data server, data http-service (get).

something this: <input type="date" [value]="..."> know <input type="date"> require string, , create interface in component: 

   export interface idatetime {     createdat: string;    }

and of course add property in component: 

public datetime: idatetime = {createdat: ""};

finally, in template add tag:

<input class="form-control" type="date" [value]="idatetime.createdat"/>

and i've got error: cannot read property 'createdat' of undefined. tell me please, why cannot read property, , how solve problem.

thank you.

you aren't binding variable declared in component, rather attempting bind interface declaration's property. bind variable instead need have [value]="datetime.createdat"
