Strange behavior in angularjs - angularjs

Question

I have a Home page where I display set of data fetched from a $http.get function.
Well, the first time the page loads, it's displayed perfectly, but if you reload the page, it arises the following error:
angular.js:13550 SyntaxError: Unexpected token < in JSON at position 695
at Object.parse (native)
Now, if I go to another page and come back to Home page, it works fine. And if I reload again, it arises the same error.
I'm struggling trying to guess what's happening.
Here I post the init function:
$scope.init = function() {
functions.loading($scope.loading, true);
$scope.$on('loading', function(evt, value) {
$scope.loading.state = value;
});
angular.element(document).ready(function () {
searchService.search_stats().then( function(response) {
FusionCharts.ready(function(){
var last7days = new FusionCharts({
"type": "column2d",
"renderAt": "last7days",
"width": "100%",
"height": "300",
"dataFormat": "json",
"dataSource": {
"chart": {
"caption": "Volume of Searches - Graph",
"subCaption": "Last 7 days",
"xAxisName": "Last 7 days",
"yAxisName": "Volume of searches",
"theme": "fint"
},
"data": response.data.last7days
}
});
last7days.render();
var search_countries = new FusionCharts({
"type": "maps/world",
"renderAt": "search_countries",
"width": "100%",
"height": "400",
"dataFormat": "json",
"dataSource": {
"chart": {
"caption": "Search Volume by Country - Graph",
"subcaption": "Last 7 days ",
"entityFillHoverColor": "#cccccc",
"numberScaleValue": "1,1000,1000",
"numberScaleUnit": "K,M,B",
"numberPrefix": "$",
"showLabels": "1",
"theme": "fint"
},
"colorrange": {
"minvalue": "0",
"startlabel": "Low",
"endlabel": "High",
"code": "#e44a00",
"gradient": "1",
"color": [
{
"maxvalue": response.data.max/2,
"displayvalue": "Average",
"code": "#f8bd19"
},
{
"maxvalue": response.data.max,
"code": "#6baa01"
}
]
},
"data": response.data.countries
}
});
search_countries.render();
functions.loading($scope.loading, false);
});
});
functions.containerResize();
});
search_stats is in a Factory:
search_stats: function(a) {
return $http.get('/api/myFunctions/search_stats/', {cache:false});
}
Any idea?

Well,
Now, at least, I could guess what's happening.
For some strange circumstance, in Chrome was activated Development mode and when switch it off, the page works fine and no error arises now.
