Passing a string variable from a view to backend model

So this seems like it should be an easy one, but I seem to be unable to figure it out.  I have a sitebuilder site built off of the reference cart (denali) that I want to be able to take value in window.name and pass it to the suitescript .model.js file so that I can use the value in a search.  Basically I want the namevariable in the following to be set by window.name

       var filters = [            new nlobjSearchFilter('custrecord_owner', null, 'anyof', nlapiGetUser()),            new nlobjSearchFilter('name', null, 'is', namevariable)          ];          var columns = [            new nlobjSearchColumn('internalid'),            new nlobjSearchColumn('name'),            new nlobjSearchColumn('custrecord_genre')          ];          var search = nlapiSearchRecord('customrecord_artist', null, filters, columns);       //   if (search && search.length === 1) {       //     return {              result.internalid= search[0].getValue('internalid'),              result.name= search[0].getValue('name'),              result.genre= search[0].getValue('custrecord_genre')
