how to filter in angular2-tree

I am trying to implement angular2-tree in my application, and its work great but when i try to add filter i am not able to figure out how to get the tree object which is used for filter.

here is link for angular2-tree docs https://angular2-tree.readme.io/docs/filtering

here is my html 

<input #filter (keyup)="filterNodes(filter.value, tree)" placeholder="filter nodes" />
<Tree (onMoveNode)="onMoveNode($event)" [nodes]="nodes" [options]="customTemplateStringOptions"></Tree>

here is my ts code for filter

filterNodes(text, tree) {
   tree.treeModel.filterNodes("text", true);
};

but i am not able to get the tree object

<input #filter (keyup)="filterNodes(filter.value, tree)" placeholder="filter nodes" />
<Tree #tree (onMoveNode)="onMoveNode($event)" [nodes]="nodes" [options]="customTemplateStringOptions"></Tree>

In you component code:

@ViewChild('tree') tree: any;

And then it should be defined in the component

Let me know if it solved your issue
