What is model in routing with parameters ?

I am following the walkthrough series and came across the Routing with parameters tutorial at Step 32: Routing with Parameters .

I am trying to understand the details that are to be passed in the _onObjectmatched function

_onObjectMatched:function(oEvent){
this.getView().bindElement({
path:"/"+ oEvent.getParameter("arguments").invoicePath,
model:"invoice"
});

As in the example in the tutorial the model is provided as invoice. What is the model name that to be taken/ given in our application? I am using WEBIDE templates. Is it specified during project generation or any model name can be specified ?

I am unable to bindelement to the view now.
