Hi All,

You don't have to pass the data to any page.
onInit method of controller set your oData model like this.
              onInit: function() {
              //var oModel = sap.ui.model.json.JSONModel();
              var oModel = sap.ui.model.json.JSONModel("http://services.odata.org/V3/Northwind/Northwind.svc/Customers?$format=json");
              sap.ui.getCore().setModel(oModel,"oDataId");
After this you can access your model from any views by just binding the elements with your odata. Suppose i have a table in a view of my application then i can write like this.
              var oTable = sap.ui.table.Table({
                     tableId: "myTable",
                     visibleRowCount: 5,
                     editable: false
              oControl = new sap.ui.commons.TextView({text: "{CustomerID}"});
              oTable.addColumn(
                           new sap.ui.table.Column({                             
                           label: new sap.ui.commons.Label({text: "Customer ID"}),
                           visible:true,
                           template: oControl  
              oControl = new sap.ui.commons.TextView({text: "{ContactName}"});
              oTable.addColumn(
                           new sap.ui.table.Column({                             
                           label: new sap.ui.commons.Label({text: "Contact Name"}),
                           visible:true,
                           template: oControl  
              oControl = new sap.ui.commons.TextView({text: "{ContactTitle}"});
              oTable.addColumn(
                           new sap.ui.table.Column({                             
                           label: new sap.ui.commons.Label({text: "Contact Title"}),
                           visible:true,
                           template: oControl  
              oControl = new sap.ui.commons.TextView({text: "{CompanyName}"});
              oTable.addColumn(
                           new sap.ui.table.Column({                             
                           label: new sap.ui.commons.Label({text: "Company Name"}),
                           visible:true,
                           template: oControl  
              oTable.bindRows("oDataId>/value");
Here you can see i have binded the oData with table.
Just what i am seeing that you are trying to pass this model to a page. You don't have to do so. Just bind your oData with relevant elements lite table or anything by writing like this.
oTable.bindRows("oDataId>/value");
these functions are different for different elements.
for listItem you may write like this.
              var oList = new sap.m.List({
              inset: true,
              items : [
                                    new sap.m.DisplayListItem({ label :"Category ID", value : "{oDataId>/CategoryID}"}),
{oDataId>/CategoryID} this has been used for binding.
