Data binding working ... now a question about the variables

Question

I wrote a small app based on the example (below) from sapui5.hana.ondemand.com.
My question pertains to anyone else that has data binding working and has tried to do something like the text in red.
When stringing together "variables" like the ones highlighted in below ... if I do something similar all I get on the screen is the actual text, ie {Width} instead of the value that should replace that.  If I get rid of the extra text and just have the variable in " " I get the correct value displayed for the "variable"
Anyone else ran across this?

Thanks for the reply Chandra,
To clarify a bit more, I have a list object and have successfully been able to bind a model to it.  When I create a list item to put in the list I can display the correct values using the same syntax as above, ie {Width}
So I am not binding the model to the items in the list rather to the list itself then referring to fields that are available in the model using the syntax {Width} ... and this works fine ... until I try and add some additional text like {StgeBin} in the example below (I am including myHeader in the list that has a model bound to it):
var myHeader = new sap.m.ObjectHeader({
        title : "Bin # {StgeBin}",   //This shows the text --> Bin # {StgeBin}  ... rather then Bin # 123  (which is what I want)
        //title : "{StgeBin}",        This works and will show the bin number as I expected ie 123
        statuses : [
          new sap.m.ObjectStatus({
            text : "Some Damaged",
            state : "Error"
          new sap.m.ObjectStatus({
            text : "In Stock",
            state : "Success"
        attributes : [
          new sap.m.ObjectAttribute({
            text : "{StgeLocDesc}"
          new sap.m.ObjectAttribute({
            text : "{Material}"
          new sap.m.ObjectAttribute({
             text : "{MaterialDesc}"
I took this example right from the SAPUI5 documentation and it works great, just can't add additional text inline with my variables.
