I am trying to call a function by registering a pick action then using ExecuteCodeAction. The function call works properly when called from an if, but throws an error when I click on the sphere. Here is the code in playground:  
[https://www.babylonjs-playground.com/ts.html#V2G1XI#17](https://www.babylonjs-playground.com/ts.html#V2G1XI#17)

The error is  
Uncaught TypeError: this.func is not a function  
at t.execute (babylon.js:16)  
at t.e.\_executeCurrent (babylon.js:16)  
at t.processTrigger (babylon.js:16)  
at e.\_processPointerUp (babylon.js:16)  
at babylon.js:16  
at e.\_initClickEvent (babylon.js:16)  
at \_onPointerUp (babylon.js:16)

Any advice?

Hi @drburton  
you need to encapsulate it in another function, [https://www.babylonjs-playground.com/ts.html#V2G1XI#18](https://www.babylonjs-playground.com/ts.html#V2G1XI#18)

Or a separate function checking the evt then calling pushMesh
