javascript context issue - parameters undefined

Question

I have this code:

targetMu: function(programmeCode, muId) {

//Parameter values are fine here

  targetMuController.targetMuView.on(\"targetMu:afterRender\", fun         


        

Answer 1

try to remove parameters from anonymous function:

targetMu: function(programmeCode, muId) {
    targetMuController.targetMuView.on("targetMu:afterRender", function() {       
        this.renderCustomWidgets(muId, programmeCode);
    });
}

Answer 2

, function(programmeCode, muId) {

You just declared new parameters in the callback function with the same names.

Inside the callback, these names refer to the inner parameters – whatever was passed to the callback.
