How to integrate a trigger in BIS_fnc_initLeaflet?

[CPT_ALPHA 0]

 

I want to insert a trigger inside a "BIS_fnc_initLeaflet", which displays an image when I press space in a document. I have the following code, but it doesn't triggermision1, it doesn't affect it.

 

["init", [this, "MISION 1.jpg", "INFORMATION", {triggermision1 = true;}]] remoteExec["BIS_fnc_initLeaflet", 0 ];

Thank you all.
