So lets have following markup for PrimeNG table 

```html
<p-dataTable
    selectionMode="multiple"
    [(selection)]="selectedUsers"
    dataKey="id"
    [value]="users">

```

There obviously is a difference between `selectionMode="multiple"` and `[selection]="multiple"` as second variand does not make table selectable. What is the difference??

For a moment i thought that `property=` will set value once while `[property]=` would bind that property to input value so it would reflect its changes, but if that is the case, in both variants table should behave the same in my case.
