Ion-searchbar with device keyboard

HI There,

I am having an issue with ion-searchbar. When user presses the “Search” button in the device keyboard it clears up the text in the search box. However, we have button in the app of course that works; calls the custom search method. Question, how do I integrate the app custom search functionality (which is called from a button press) with the device keyboard “Search” button? I will appreciate help in this.

<ion-searchbar [(ngModel)]="queryLname" placeholder="Type a Last Name"></ion-searchbar>
