NativeScript with angular gives a run time error - nativescript-angular

Question

I just tried a connect with my Native-script app.In app.component.ts file i have create my database and two methods.
export class AppComponent {
private database: any;
private people: Array<any>;
public constructor() {
console.log(" database service constructors");
(new Sqlite("my.db")).then(db => {
db.execSQL("CREATE TABLE IF NOT EXISTS people (id INTEGER PRIMARY KEY AUTOINCREMENT, firstName TEXT, lastName Text)").then(db => {
this.database = db;
}, error => {
console.log("CREATE TABLE ERROR", error);
})
}, error => {
console.log("CREATE DB ERROR", error);
})}
public insert() {
console.log("Acess Insert Ok");
this.database.execSql("INSERT INTO people (firstName, lastName) VALUES (?,?)", ["Randika", "Perera"]).then(id => {
console.log("Insert Ok");
this.fetch();
}, error => {
console.log("INSERT ERROR: ", error);
})}
public fetch() {
this.database.all("SELECT * FROM people").then(rows => {
this.people = [];
for (let row in rows) {
this.people.push({
"id": rows[row][0],
"firstName": rows[row][1],
"lastName": rows[row][2]
})
}
}, error => {
console.log("SELECTOR ERROR:", error);
});}}
In app.component.hlml file:
<ActionBar title="My App">
<ActionItem text="Add" (tap)="insert()"></ActionItem>
But after clicking add button and it gives a error like
W/System.err(10737): at com.tns.Runtime.callJSMethodNative(Native Method)
W/System.err(10737): at com.tns.Runtime.dispatchCallJSMethodNative(Runtime.java:1197)

When i'm searching more on it in emulator there is a error like " execSql is not a function". so i change it to execSQL like i used top of the and now its working fine.
