SAPUI5: getModel returns undefined if called within the same function of setModel

I'm trying to set a model and retrieving it from OData after pressing a certain button.

The problem is when I call getModel outside of the "success" function, it returns undefined.

Because "onPressButton1" runs fully before the "success" function gets executed.

So is there a way to make sure "success" function is called first? and within the onPressButton1.

If I put my whole code in "success" function, I'll not be able to use "this" key word to call functions "this.fDoThis();"

Code for reference:

onPressButton1: function() {
	var vEntityURL = "/CustomerSet(ID='000')";
	var sServiceUrl = "/Customers_SRV/";
	var oServiceModel = new sap.ui.model.odata.ODataModel(sServiceUrl, true);
	var oJsonModel = new sap.ui.model.json.JSONModel();, {
		success: function(oData) {
		sap.ui.getCore().setModel(oJsonModel, "Customers");

	var oCustomer = this.getView().getModel("Customers");

    Use V2 odata model, v1 is deprecated.

    Try chanfing the success handler as shown below. Add.bind(this) and set model to view

    success: function(oData) {
    		this.getView().setModel(oJsonModel, "Customers");

    • Thanks now I'm able to use "this". However, any chance in making the success runs before its parent function?

      for example the following returns an error in console unless button is pressed twice:

      	var vEntityURL ="/CustomerSet(ID='000')";
      	var sServiceUrl ="/Customers_SRV/";
      	var oServiceModel =newsap.ui.model.odata.ODataModel(sServiceUrl, true);
      	var oJsonModel =newsap.ui.model.json.JSONModel();
      	var oCustomer = this.getView().getModel("Customers");
