Backend Api undefined

Hello, I try to develop an extention for qlik sense. I would want to use the Backend Api but I get this message:

Uncaught TypeError: Cannot read property 'selectValues' of undefined

node

.on("click", function(d){

this.backendApi.selectValues(0,[1,2],true);

});

Where's my mistake?

Thank you!

thank you!!

"this"- in your code refers to the element for which you have bound the click event.

The Backend API is available for extension developers as this.backend API, in order to have the backend API to work you should use "this" which is referring/points to the extension itself

Example

var self = this;
// referring to the extension itself & should be declared within the paint method

$element.on('click',function(){
var value =[1,2];
self.backendApi.selectValues(0, value,true);

});
