Class not found

[NareshKukreti12]

Hi @cakuki I am getting class not found error in ionic 3. I am testing on android device. This is my code -
HTML
<div class="date-label" (click)="show()">No date selected</div> <div class="inline-datepicker" ></div>

.ts

`declare var cordova:any;
this.element = (document.querySelector('.inline-datepicker') as HTMLDivElement);
show(){

console.log("Element", this.element)
let options = {
'mode': cordova.plugins.DatePicker.Mode.DATE,
'date': new Date(),
};
let success = (data)=> {
alert('success');
}
let error = (data)=> {
console.log("err",data);
}
cordova.plugins.DatePicker.create(this.element, options,success, error);
cordova.plugins.DatePicker.show(this.element, options,success, error);}

What am I doing wrong?
